And make sure you have gone through the problems mentioned in the error chapter. Welcome to the CanonDisk ------------------------ CanonDisk is software for controlling Canon printers with the Commodore-Amiga personal computer with the purpose of creating high quality output. The CanonDisk is divided into two parts, a Canon driver and a Canon picture-printing program. CanonDisk's main qualities include: * Workbench printer drivers for all current BJ and BJC Canon printers. The drivers have been designed specifically for each printer and give several unique features. * The BJ5-230 and BJC drivers support Canon's Extended Emulation for faster and improved graphic output. * Definable dither patterns including preset patterns. * 16-point colour adjustment for each colour component. This gives the user many features including gamma correction, and contrast and brightness adjustment. * Ink compensation for the correction of ink impurities. * Workbench 2/3 graphical user interface (GUI). * The Canon drivers can print up to 256 shades of grey from normal Amiga applications. Standard Amiga drivers are limited to 16. * Settings for page size, paper margins and the size of graphics to be printed. * Settings for built-in printer typefaces. * The software is very fast and automatically uses improved routines if the software is run on an Amiga with a 68020/30/40 CPU. * Includes a very fast printer drivers for the PageStream DTP package. * font generation and automatic font download to the printer. * A limited working version of the CanonStudio graphic printing program. These are not the complete capabilities of the CanonDisk, merely some of the highlights. System Requirements ------------------- CanonDisk is compatible with the entire family of Amiga computers. These include the A500, A1000, A1200, A1500, A2000, A2500, A2500/30, A3000 and A4000. CanonDisk was designed to run under Workbench versions 2, 2.1, 3 and 3.1. How CanonDisk Is Documented --------------------------- CanonDisk is very easy to use, but you do require at least a passing familiarity with general Amiga usage and practices. This readme manual assumes that you have such a familiarity. If more basic information is required about operating your Amiga than is provided in this manual, please consult the introductory manuals that came with your machine. We also strongly suggest that new Amiga owners contact their local Amiga user groups for basic training and help. In order to produce the best product possible the manual is routinely updated each time a new run is required. If you should find any technical, typographical, grammatical or any other type of error in your manual, please relay this information clearly to the developer (address see above). Thanks to... ------------ I have been assisted by testers and those who have sent money, printer manuals and program suggestions. To all of you, I extend my appreciation. Because of their extra efforts I would like to thank following people and companies: Jeff Walker, the person who dragged me into the chaotic world of writing printer software (bah!), and who proof read most parts of this manual and re-worded parts of it. Canon, surely the only printer manufacturer with major Amiga development and support. - Wolf Faust, December 1992. The Workbench Printer Drivers ----------------------------- After installing a Canon driver you should be able to print from your normal application programs. In most cases you must further adjust the driver settings to your printer to get the best printer output possible. This chapter describes most of the functions for controlling the Canon drivers. But before describing each driver, here are some general things about printer drivers, and in paticular the Canon drivers. GRAPHIC >-------------- | | \|/ ----------- TEXT >------> | Driver | >-------> PRINTER ----------- /|\ | | | Preferences Printer drivers offer a way of sending configuration-independent output to a printer attached to the Amiga. A driver can be thought of as a filter that takes standard commands as input, and translates them into commands understood by specific printers. The commands sent to the printer via the prt: device are standardized on all Amigas so that programmers only have to write the software once and not for all possible printer emulations. It is the task of the printer driver to translate an Amiga printer command into the correct command for a particular printer. For each type of printer in use, a printer driver (or a driver for a compatible printer) should be present in the devs:printers directory. If you want to print text in bold, you have to decide whether to use a standard Amiga command (also known as an escape sequence) via prt:, or the command mentioned in your printer manual via par:. Often people get confused about prt: and par:. Do not send commands mentioned in your printer manual to prt:. This will most likely fail, or cause wrong characters in your printer output. You should user prt: as opposed to par: because commands send to prt: can be used on every printer, not just the kind of printer you have. The par: device has even more shortcomings than prt:, but we're not concerned with them in this manual. An argument often used by programmers using par: is the unlimited control over the printer. This is a fallacy. You can control every printer feature via the prt: device. The Canon Printer Drivers ------------------------- The Canon printer drivers automatically check for the processor being used (68000, 68010/68020, 68030, 68040) and optimize the print routines accordingly, so there is no need for a special `turbo' version of the driver in order to get the most out of your Amiga. The tables below show the graphics densities supported by all the Canon drivers. Density is set in Workbench preferences. With some programs you can also choose a density from within your application program. Beside the density tables, tables with all driver-supported Amiga escape sequences (use prt: not par: for these commands) are shown.

CanonDisk includes special printer drivers for the PageStream 2.x desktop publishing program. These drivers offer major speed improvement compared to the normal PageStream driver as they use Canon's Extended emulation. The installation of the PageStream drivers is performed by the normal CanonDisk installation program. If you install a driver for a printer which might also work with the Canon PageStream drivers, the installation program will ask you whether you want to install the Canon PageStream drivers or not. The PageStream V2.x BJ2xx.printer driver supports the following settings in the printer requesters special utility: letter, legal, a4 and a3 (case is important!). The PageStream V2.x CanonBJCx00.printer is installed for BJC users. BJC 210 users should use the installed CanonBJC 800 driver. The BJC driver supports the following settings in the printer requesters special utility: Paper sizes: letter legal a4 a3 ledger BJC800 print modes: modea modeb modec moded modee BJC6x0 print modes: paper: COATED or OHP or PLAIN (default) paper thickness: NORM (default) or THICK % amount of black ink: BLACK100 (default) or BLACK200 print quality: GOOD or DRAFT or HIGH (default) No BJC6x0 print mode will be defined, unless you use one of the BJC6x0 options. For instance, you qant to print on normal DIN A4 paper as fast as possible, define "A4+PLAIN+DRAFT+NORM+BLACK100" in the PageStream special gadget. PageStream 3.x Printer Drivers ------------------------------ When using PageStream 3.x, you currently have to use the Workbench driver from PageStream 3.x as the old Canon PageStream drivers don't work with the new program. The quality and features are far from being good. That's why a CanonStudio PageStream 3.0i driver was developed. With this driver you can print from PageStream using CanonStudio with all it's features. However, the driver currently only works with the latest PageStream 3.0i version and requires a registered CanonStudio program or the Studio printing program. Users already owning reg. CanonStudio or Studio can download the driver from CompuServe's AmigaUser library or from AmiNet. The SetupBJL Program -------------------- For some Canon users a SetupBJL program is installed (by the time of this writing: only for the Canon BJC 4100 and BJC210). The program SetupBJL may also be named SetupBJL-BJC4100 or similar identifying the printer to use with. The program can usualy be found in your systems Prefs drawer beside the drivers CanonPref program. The SetupBJL program may be used by Canon BJ and BJC users for controlling the printers permanent settings. It also allows you to perform certain printer functions like test dumps and ink head cleaning. The use of this program is very similar to the MS-DOS or Windows program described in your printers user manual or DOS print guide. This chapter will only cover the additional Amiga specific functions of the setup software. See you printer manuals for more details. In most cases the printer is shipped to you by the manufacturer already setup right for use with the Amiga. Anyway, if you start SetupBJL for the first time, it's recommended to run the Setup For Amiga/EU action first. This will setup the printer for ou automaticly. SetupBJL can be started with various Tool Types or Shell arguments: PUBSCREEN: SetupBJL opens a window on the default public screen. You may specify a special public screen by setting the Tool Type "PUBSCREEN=screenname". The screen name is case sensitive. and the SetupBJL program will open its windows on your application's screen. TOPAZ: SetupBJL is font independent. All text is displayed using the system font. If TOPAZ is specified, only the topaz 8 font is used. SAVE: When using this option, SetupBJL will set-up the printer without showing the set-up window first. This is useful for controlling printer settings from batch files. You can enable certain printer settings without user interaction by using the FROM option in combination with SAVE. Settings can be saved from SetupBJL by using the Save As menu item. SetupBJL will automaticly quit after 10 seconds if your printer is off or not connected. FROM: SetupBJL saves the settings sent to the printer in a file named SetupBJL.prefs, placed in the same drawer as the SetupBJL program. Next time you start SetupBJL, the current printer settings are read from this file and displayed. FROM allows you to specify a different settings file for reading. You can save other settings files than SetupBJL.prefs using the Save As menu item. DEVICE: SetupBJL usually sets up the output device defined in Workbench 2.04 printer preferences. Since Workbench 2.04, nearly any output device can be defined in preferences for printer output. Usually serial.device or parallel.device is used. You may alter the device using the case sensitive DEVICE Tool Type or Shell argument. UNIT: Workbench 2.04 (or higher) Printer preferences programs may enable you to specify a printer port unit to print to. Most of the current multiport cards enable you to specify a port to print to using a unit number (0 = internal port, 1 = external port A, 2 = external port B ...). Using the UNIT tool type or Shell keyword you can define a unit (port) to print to. POWEROFF: When using this option, SetupBJL will turn off the printer without showing the set-up window first. This is useful for controlling the printer from batch files. SetupBJL will automaticly quit after 10 seconds if your printer is already off or not connected. SetupBJL saves the settings sent to the printer in a file named SetupBJL.prefs, placed in the same drawer as the SetupBJL program. Next time you start SetupBJL, the current printer settings are read from this file and displayed. This method works only so long as SetupBJL is used for all printer setting changes and is not moved to another directory without the SetupBJL.prefs file. SetupBJL offers some printer functions and settings not available in the MS DOS software: Setup For Amiga/EU This Printer Action function will setup the Canon printer for use with the Canon Amiga Workbench driver. The setup is for use with DIN A4 sized paper wich is mainly used in Europe (EU). Setup For Amiga/US Same as Setup For Amiga/EU for use with US Letter sized paper. Enable Hex Dump This Printer Action will set the printer to hex dump mode. Auto On When enabled, the printer will automaticly turn on if you try to transfer data to the printer. The option is usefull in combination with the Auto Off setting. It allows you to let the printer automaticly turn itself on and off as needed. Please note that turning on your computer can cause the printer to go on too. This is a normal behaviour with Auto On enabled. Turning your printer on and off too often is also no good idea. The printer does consume a small amount of ink for a cleaning procedure everytime it is turned on. It is recommended to use the Auto Off feature with at least 10 minutes. The Canon Preferences Programs ------------------------------ Apart from the functions mentioned in the section "The Canon Printer Drivers", there are more utilities unique to the Canon drivers. These utilities are managed using Commodore's standard environment variables and can be controlled by using the Shell setenv and getenv commands. As setting environment variables this way can be a very complex task, a Canon preferences program is available to make the job easier. The CanonPref preferences programs provide an intuitive GUI and requires at least Workbench 2.04 to run. The CanonPref preferences programs can be controlled by the mouse and/or the keyboard. Each gadget in the program can be operated by pressing the underlined letter in the gadget. Pressing that letter is equivalent to clicking on the gadget with the mouse. In the case of a cycle gadget, you can use the upper case or lower case letter to cycle back and forth. See your Amiga system manual on how to control the filerequester by keyboard or mouse. Following Canon preference editors are available on this CanonDisk (from now on I will call them CanonPref programs): Driver Preference Editor Setting file ENV: ------------------------------------------------------------------ CanonBJ300 CanonBJ300Pref CanonBJ300Pref CanonBJ5-230 CanonBJ5-230Pref CanonBJ5-230Pref CanonBJ-EC CanonBJECPref CanonBJECPref All windows are opened directly under your mouse pointer, so you do not have to move or scroll the screen to control the program. All windows are opened on the default public screen. You may specify a special public screen by setting the Tool Type PUBSCREENscreen name The screen name is case sensitive. and the CanonPref preferences program will open its windows on your application's screen. If you run the preferences program from a Shell You can specify a screen with the PUBSCREEN option: CanonBJECPref PUBSCREEN screenname For example, if you use the ASDG CEDPro text editor you may specify CanonPref PUBSCREEN CygnusEdScreen1 and the CanonPref preferences program will open its windows on the CEDPro screen. Make sure the CEDPro screen is public before running the example. You need at least CEDPro version 2.12 for this example. All Canon programs are font independent, which means they use any system font you have chosen in Workbench Font preferences for displaying the text in gadgets and windows. You can force the preferences programs to always use the topaz 8 font by defining a TOPAZ Tool Type. This is the same as using a TOPAZ Shell argument. Similar to the preferences programs that comes with the Workbench system, the USE, SAVE and FROM Shell arguments or Tool Types allow switching between different driver settings. You can specify the preference file to edit with the FROM argument. If you combine FROM with the USE keyword the settings of the specified preference file will become temporarily enabled. The preference program will not show any user interface. SAVE is similar to USE except that SAVE enables the settings permanently. SAVE may be used without the FROM keyword in order to make temporary settings permanent. You can save a driver preferences file using the Save As... menu item in the preferences program. Preference files cannot be exchanged between different drivers. After starting a driver preferences program, the main window opens. Now continue reading the chapter which discusses the driver preferences program that has been installed by the installation program. The name of the preference program is displayed at the end of the installation and should have been noted along with the driver name. All CanonPref program are very similar. All utilities in the CanonPref programs are described here in detail: Emul.: Print Mode: ----------- Most new Canon printers do offer a so called "Extended Emulation". This emulation is only support by Canon printer drivers. Using Extended Emulation limits printing to graphics as no internal printer font can be used by the emulation. But graphics are printed much faster and/or in higher quality using the Extended emulation of the printer. So it's worth switch emulation for graphic printing. The Emul. and Mode gadgets allow you to select the required text and graphic emulation for printing. Some emulations offer special print modes selected by Emul. mode. Here are the main differences between the various emulations and print modes supported: Epson24 / BJ printers This emulation can be used with most currently available 24-pin printers. The emulation supports printing text and graphics. Two passes of the printer head are needed for printing one line of graphics at 360 vertical dpi. The emulation is also supported by BJ printers with Epson emulation. Epson48 / BJC printers This emulation is the driver's default setting. The emulation supports printing text and graphics. The emulation is not supported by most BJ printers. The emulation is able to print 48 dots per printer line in 360 dpi resolution, enabling the printing of high density graphics in one pass per line. BJ 200/230 Graphics only BJ 200ex Graphics only This emulation does not support printing text. Graphic printing is accomplished using the printer's extended emulation. The emulation is for use with BJ-200, 200e, 200ex and BJ-230 printers only. The emulation supports printing up to 64 dots per printer line. Compression is used by the driver to speed up transfer of data to the printer. The 200ex mode also allows you to define the print mode of the printer. Use the print mode gadget. BJC 600(e) Graphics only This emulation only supports graphic dumps. Any text will not be printed, and usually an empty page is ejected. Different to the Epson emulations, the BJC 600 Graphics only emulation supports printing up to 64 dots per line. When using the Canon BJC emulation you are able to define the print mode or method. For the BJC-600 you can choose various paper types (normal/plain, coated, back print film and transparency/OHP), paper thickness (normal, thick) and print quality (enhanced black, high speed, high quality). The print quality and paper type setting has a major influence on the printed speed. BJC 610 Graphics only This emulation only supports graphic dumps. Any text will not be printed, and usually an empty page is ejected. Different to the Epson emulations, the BJC 610 Graphics only emulation supports printing up to 64 dots per line and 720dpi. When using the Canon BJC emulation you are able to define the print mode and method. For the BJC-610 you can choose various paper types (normal/plain, coated, back print film and transparency/OHP). The paper type setting has a major influence on the printed speed and quality. Please note that as soon as you select 720dpi for printing, you usualy have to adjust the colors of the output. You can use the Preset menu of CanonBJECPref for this. It offers a color preset for the BJC 610 and various paper types. BJC 800 Graphics only This emulation only supports graphic dumps. Any text will not be printed, and usually an empty page is ejected. Different to the Epson emulations, the BJC 800 Graphics only emulation allows control over the print mode used. The print mode set by the printer panel is overridden. Please see your BJC-800/820 printer manual for more information about each print mode offered. For the best quality select print mode A. BJC 4000 Graphics only BJC 4100 Graphics only BJC 70/BJ 30 Graphics only This emulation only supports graphic dumps. Any text will not be printed, and usually an empty page is ejected. Different to the Epson emulations, the BJC Graphics only emulation supports printing up to 128 dots per printer line (BC 20 cartridge with BJC 400 or BJC 4100). When using the Canon BJC-4000, BJC 70 and BJ30 emulation you are able to define the print mode or method. You can choose various paper types (normal/plain, coated, back print film and transparency/OHP), print quality (high speed, high quality, also known as fine mode). The print quality and paper type setting has a major influence on the printed speed. Please note only the "BJC 4100 Graphics only" mode allows printing graphics with up to 720*360dpi on the BJC 4100 printer. As soon as you select 720*360dpi for printing on the BJC 4100, you usualy have to adjust the colors of the output. You can use the Preset menu of CanonBJECPref for this. It offers a color preset for the BJC 4100 and 720*360dpi on normal xerox paper. Smooth: ------- The Smooth gadget is only available when "BJC 4000 Graphics only", "BJC 600e Graphics only" or "BJC 70 / BJ 30 Graphics only" emulation is enabled. The Smooth mode requires a BJC-4000 with the BC-20 b/w cartridge and a BJC 70 (ie. BJ 30) with the b/w only cartridge. When smoothing is enabled, the printer refines your printout by polishing away jagged edges and ragged stair-stepping curves of graphics. This results in sharp and crisp printout at 720 (horizontal) by 360 (vertical) dots per inch. Note that printing speed is affected by smoothing. The printer's smooth dip switch setting does not affect printing in BJC emulation. Color Mode (Supergrey): ------------------------ Normal Workbench printer drivers are limited to 16 shades of grey. After brightening the graphics output, even fewer shades are available. Canon drivers do not have this limitation and can print colour pictures in up to 256 shades of grey using the Workbench color output mode. Some Canon drivers provide a Supergrey gadget allowing you to switch between real color output and Supergrey mode. This gadget is not needed by b/w BJ drivers. With Supergrey enabled, every colour picture will be printed as a greyscale picture if you select colour instead of greyscale as the graphics output mode. With Supergrey it is the printer driver's task to convert the colour data into greyscale data. While this can be done by the printer device instead of the printer driver (as normal Workbench drivers do), the Canon printer driver colour-to-greyscale conversion routines are more precise. Because of this you can print a 4096 colour HAM picture in up to 256 shades of grey instead of the normal 16 shades. Supergrey will replace the normal colour dump of the driver. If you want to print more than 16 shades of grey (and that's what Supergrey is all about!) you must define a custom dither matrix in the CanonPref program that enables you to print more than 16 shades. Defining a dither matrix using CanonPref is described later. Supergrey works with nearly every Amiga application simply by printing in Workbench's colour mode, even if your printer isn't a colour printer. Application programs that provide their own dither routines should not be used with Canon's custom dither routines, and because of this should not be used with Supergrey . Programs with custom dither routines include Art Department Professional's PrefPrinter saver, TruePrint24 and PageStream V2.x (not V3!). The CanonStudio picture-printing program also belongs to this category of programs, but it automatically detects whether you are printing in Supergrey or colour. The CanonStudio program automatically prints pictures as greyscales if Supergrey is enabled. Supergrey can be disabled in several ways. Take care that none of the following special cases are in effect if you want to print pictures using Supergrey: * Canon's custom dither and colour correction routines can be turned off by printing with a Workbench density below 3. Because of this, Supergrey works only with graphics densities above 2. * Canon's custom dither and colour correction routines can be turned off by printing with a Workbench dither method other than ordered . Because of this, Supergrey works only with the ordered dither routine set in Workbench preferences. This does not mean that you cannot print a halftone dither with Supergrey . You just have to use the Canon dither routines set in CanonPref instead of the dither routines set in Workbench preferences, because only the Canon dither routines offer more than 16 shades of grey. * Supergrey can always be turned off using CanonPref. Table below shows all parameters that must be enabled for printing with Supergrey: Function Density Workbench-Dither Supergrey >2 Ordered In Compensation >2 Ordered Color Adjustment >2 Ordered Custom Dither >2 Ordered Note: the number of printable shades of greys in Supergrey depends on the number of shades supported by the dither method set in CanonPref. Up to 256 shades are possible, and supported by the Canon dither routines. Often a dither method that produces 64 shades of grey gives the best results. Separation: ----------- You may print separations with the help of the separation utility in the upper right half of the window. Each primary colour that is checkmarked will be printed (C=cyan, M=magenta, Y=yellow, K=black). An example of the use of the separation function can be found in the tips and tricks chapter. Mirror: ------- If set to on (with a checkmark), graphics will be mirrored; especially useful if you want to print pictures intended for T-shirt art. LineFeed: --------- Many printers exibit 'banding' unwanted horizontal stripes when printing graphics. This is often caused by mechanical inaccuracies in linefeeding - either slightly too much or too little, causing dark or white horizontal lines. LineFeed gadget allows you to adjust the driver to the mechanical inaccuracy of the printer. Set LineFeed to -1 if you have white lines in the output, or +1 if you have dark lines. Textcolor: ---------- With the Textcolor cycle gadget you may choose the default text colour for the printer. Typeface: --------- The Typeface gadget allows you to define the printer's typeface (or `font') selected by the aFNT0 (see the command tables above). The typeface selected with aFNT0 is your default typeface. Font Download: -------------- If you enable this function (checkmark on), the CanonBJ5-230 driver will automatically download fonts created by you or the FontShop program. In the event that you don't need the download feature, you can disable this feature without deleting or moving the font files. Timeout: -------- Most people know the "Printer trouble..." requester well. This system requester most often appears when you print a document that is several pages long. The requester is caused by the computer not transferring waiting data to the printer for a period of time (usually 30 seconds). If there is a `timeout' the printer device assumes an error and the requester appears. A timeout may also appear without a real error happening if your printer is waiting for (or slowly feeding in) a new sheet of paper, for example. This operation often needs more than 30 seconds, and during this time no data is accepted by the printer. With Timeout you can specify a higher timeout value, resulting in fewer timeout requesters. A value from 1 to 999 seconds is allowed (default 30 seconds). Instead of defining a huge timeout value there is another solution available: use the CMD program (see your Workbench disk) to redirect the parallel/serial output to a file on disk. After this, use the Copy command or a printer spooler to copy the file to par: . This technique may also result in a better output quality, especially with inkjet printers. Note: If there is a real timeout error you will have to wait the number of seconds specified by Timeout until an error requester appears, thus allowing you to cancel the print job. So choose your Timeout value wisely. Job End: -------- If the printer device closes after a dump, you can tell the driver to signal the end of the print job. This is especially useful on huge graphic dumps which might require some time. There are two kinds of signals. You can cause a beep (Ctrl-G) on the printer, a DisplayBeep on the Amiga, or both. arXon Port: ----------- All Canon drivers support the arXon parallel switch-box, an external 1 to 3 Centronics switch controllable by software. You can ask the printer driver to automatically switch to the required port for printing, and switch back to the previously used port after printing. This enables you to use a scanner, a digitizer and a printer from your Amiga's parallel port without having to switch between the devices manually. If you specify Default as the port, no switching will take place. Information about the arXon switch-box may be obtained from: arXon GmbH Assenheimer Str. 17 D-60489 Frankfurt Germany Tel: 069-987410-26 Fax: 069-987410-30 The environment variable "sbox_active" must be specified before using the driver in order to enable the switch-box feature of the driver. This is because "sbox_active" is used to determine whether a switch-box is installed or not. "sbox_active" is defined by the arXon software. Save: ----- You may leave the CanonPref by clicking on the "Save" gadget. Changes made to the settings will be saved for permanent use. Use: ---- You may leave the CanonPref preferences program by clicking on the "Use" gadget. Changes made to the settings will be saved temporarily and will stay active until you reboot the computer or change the settings using CanonPref again. Cancel: ------- You may leave the CanonPref preferences program by clicking on the "Cancel" gadget. Changes made to the settings will not be recognised or saved. More control windows -------------------- There are four utilities in the bottom half of the main CanonPref window. The ellipsis (three dots) in these icons means that another window will be opened when you select the utility. Here is a detailed description of each of the four windows. "Customize Tabulators...": -------------------------- The gadgets in this window lets you customize the horizontal tab stop settings of your printer, useful for printing program listings and tables. Up to 32 tab stops may be defined with the Canon BJ-EC driver (BJ mode drivers normally allow up to 28 tab stops). All tab stops above the limit of 32 (28) are ignored, and a requester will tell you so. Horizontal tabs are usually selected and stored by the printer in characters, not inches. Thus, any change in the character spacing can change the physical locations of horizontal tabs, but the logical positions remain unchanged. You can set or unset a tab stop by clicking on the gadget at the required position. A "T" is used for a tab stop. The "-" and "+" characters are used to help you find the correct position. Using the slider below the gadget you can scroll the `tab stops' slide to the required position. Clear Tabs: ----------- With Clear Tabs you can clear all tab stops. Set every n chars: ------------------ With the n: and Set every n chars gadget you can easily set tab stops with the same distance. Simply enter the distance into the "n:" integer gadget and select "Set every n chars". Note: the printer driver uses a default distance of eight characters. If you want to reset your customized tabs stops settings to the printer default values, simply call up "Customize Tabs..." and the window will open with a default n: value of 8. Press "Set every n chars" to select the default value. Use: Cancel: ------- You can leave the window with the "Use" or "Cancel" gadget. Changes made to the tab stops settings are accepted with Use. Cancel leaves the tab stops unchanged, and any changes made will be lost. Note: Use does not save the changes made to your environment. This is done by using the Use or Save gadget in the main window. "Page Size and Margins..." -------------------------- The gadgets in this window let you customize the paper size and margins. This window contains many additional settings that are unknown to most normal printer drivers. Enable Form: ------------ If Enable Form is checkmarked, page length (as set in Workbench preferences), Top Margin and Perforation Skip will be enabled by the driver. In order to stay compatible with normal Workbench printer drivers, the default settings are not used. Some applications require well-defined paper sizes and margins for printing forms. The Canon driver provides you with these facilities by checkmarking Enable Form. It may require some experimentation (and paper) until you have found the correct values for a specific application. Top Margin: ----------- Top Margin specifies the top margin as a number of lines. The top margin defines the vertical distance between the top of the printable area of the page and the the first line of text on the page. Using this gadget, together with the preference settings for left margin, right margin and page length, you have total freedom to define the margins of a page. Using the default value of zero disables the Top Margin function. The Top Margin is only enabled if Enable Form is checkmarked. Perforation Skip: ----------------- Perforation Skip specifies the number of lines that the printer skips over at the end of each page. This causes the printer to skip the perforation between pages of continuous forms. If zero lines is specified, perforation skip will be disabled. If the specified value is greater than or equal to the form length (as defined in the Workbench preferences program), the skip perforation is cancelled and the top and bottom margins become inactive. The Perforation Skip is only enabled if Enable Form is checkmarked. Page Length: ------------ Paper Length is a read-only gadget showing the paper length as defined in Workbench preferences. You can use the value as a guide to setting your perforation skip and top margin values. Changes made to the paper length preferences are automatically detected by the CanonPref program, and the gadget is updated immediately without the need for exiting CanonPref. The Paper Length is only enabled if Enable Form is checkmarked. Custom ResX: Custom ResY: ------------ If the selected paper format in preferences (Workbench 2.0: "Printer") is CUSTOM , this gadget allows you to specify the width of the printable area of paper in inch wide dots (LBP uses inch) . The size is used only for graphic prints and does not affect text printouts. For example, if you are using Workbench 1.3 (which doesn't have a DIN A4 option) you can specify an X resolution of 2804 1/360 inch dots (19.78cm, 7.8in), which is equal to the DIN A4 size used by most Commodore printer drivers. If you specify zero (the default) as the X resolution, the US-LETTER resolution of 2880 dots (20.3cm, 8in) will be used. The allowed range is 0 to 65535 dots. Different to the BJ300 driver, the CanonBJ5-230 driver use Custom ResX for defining the paper size including unprintable margins (0.5 inch). Similar to Custom ResX, Custom ResY defines the height of the printable paper size. Use: Cancel: ------- You can leave the window with the Use or Cancel gadget. Changes made to the settings are accepted with Use . Cancel leaves the settings unchanged and any changes made will be lost. Note: Use does not save the changes made to your environment. This is done by using the Use or Save gadget in the main window. Color Adjustments... -------------------- The gadgets in this window enable you to make colour adjustments and compensate for ink impurities. But why are colour adjustments and ink compensation needed? * Most colour printer users will have come across the problem of graphic prints being too dark, or the output containing too much red. Using the colour adjustment you can easily correct this. * The output quality of printers depends ultimately on the ink and type of paper being used. Inkjet printers are very sensitive to the type of paper used. Using the colour adjustment you can easily alter the driver to various ink and paper types. * The colour adjustment allows you to do image processing by controlling the contrast, gamma correction and brightness of each primary print colour. You can even filter out unwanted colours. * Printer inks are not completely pure materials. For example there is some yellow mixed into the magenta ink, and there is some magenta in the cyan ink. The ink compensation values will correct for these impurities allowing blues, for example, to be printed as blues rather than purples. Colour adjustment is only one of several processes needed for printing graphics. You can control the graphics output of the Canon drivers for each of these processes. Before the printer driver can process a picture for printing, it must separat it into its primary printing colours. Each primary printing colour can be adjusted by the Canon printer driver using 16 sliders which describe a conversion function. Colour adjustment is needed because the colour values displayed on computer monitors and the colours printed by printers are different. A bright red on the monitor, for example, usually is printed as dark red; blue is often printed as violet; and the printer output is often too dark. Most printers cannot print two adjacent dots without overlapping them slightly. This problem is known as `dot gain' Dot gain , causing muddy and dark output. You can avoid dot gain problems by printing with a lower resolution (for instance 180 dpi on a 360 dpi printer) or by using a special dither matrix and colour adjustment which is not affected by dot gain problems. You can control the colour adjustment sliders in several ways. There are three sliders in the upper right half of the Color Adjustments... window. These provide global control over all 16 sliders that describe the conversion function. Brightness: ----------- The brightness adjustment globally modifies the general brightness of a colour component. It does this by uniformly shifting the colour map upwards or downwards. All input intensities of one primary printing colour will be shifted upwards (made brighter) by the colour map. If you brighten all the primary printing colours, the whole picture becomes brighter. The brightness adjustment is not without its drawbacks. Notice that the darkest input value (bottom left) is brightened, leaving no darker colours for printing. This means that the darkest intensity in the image will also be brightened, which may not be acceptable. Also note that most of the brighter levels now have exactly the same intensity levels, meaning that all details which had intensity levels in that range are lost. The brightness control in CanonPref ranges from -50 to 50, with zero being the neutral value. Setting the brightness control to a positive value uniformly shifts the colour map upwards, towards a brighter colour component. Similarly, a negative value causes the colour to be shifted towards darkness. Contrast: --------- The contrast adjustment globally modifies the general contrast of a colour component. Contrast adjustments can be visualized by thinking of the neutral colour map being pivoted around its centre point. At one extreme the colour map becomes flat, which means that all input intensities map to the same output intensity (no contrast). The other extreme is a vertical line for a colour map, which produces a primary colour with exactly two intensities (maximum contrast). Notice again that contrast loses some amount of visual detail, just as the brightness adjustment does. This may or may not be acceptable for any given image. The contrast control in CanonPref ranges from -50 to 50, with zero being the neutral value. Setting the contrast control to a positive value uniformly pivots the colour map around its centre in an anti-clockwise direction (towards the vertical), which increases visible contrast. Gamma: ------ The gamma adjustment provides a way to significantly brighten a colour component without losing that much detail. It does this by introducing a curve into the colour map, whereby the colour map is shifted upwards or downwards (made brighter or darker respectively) but no portion of the colour map gets clipped to the maximum or minimum values. The gamma adjustment also affects the contrast of the colour component. In the darker part of the spectrum contrast is increased; in the lighter part of the spectrum contrast is decreased. The gamma control in CanonPref ranges from -50 to 50, where zero represents no gamma adjustment. The overall effect of gamma adjustment is usually quite satisfactory and we recommend its liberal use. There are several reasons for this. The gamma function provides an easy way to brighten a picture without losing detail. Also, monitor tubes show a computer picture using a non-linear conversion function, and this function is very similar to the gamma function. Using the gamma function allows you to more easily adapt the printer output to the monitor picture. Set: ---- Set globally sets all 16 adjustment sliders of the active colour component to the values defined by the Gamma , Brightness and Contrast sliders. Invert Bright+/- Default ------- Beside Set there are more gadgets providing global control over the 16 adjustment sliders. Invert inverts all 16 sliders. The two Bright gadgets allow you to increase or decrease the brightness of all 16 sliders. Default resets all 16 sliders to the default values used by most Commodore printer drivers (no colour adjustment). Adjustment sliders: ------------------- The 16 colour adjustment sliders in the middle of the window give you precise control over the colour adjustment function of the driver. Each slider can be set to one of 256 shades. A higher level means less of the currently selected primary colour. A lower level means more colour, causing a darker picture. All 16 sliders describe a conversion function Conversion function . Dark input values are adjusted by the sliders to the left, bright colours are adjusted by the sliders to the right. As soon as you click on one of the sliders, the value represented by the slider is shown in the Level gadget on the left-hand side of the window. Colour pictures are printed by most printers using three or four primary colours. Usually these colours are cyan, magenta, yellow and black. All 16 colour adjustment sliders are applied to one primary colour. You can choose which primary colour to adjust using the Color gadget in the upper left-hand corner of the window. But what if you want to use the gamma function to brighten a greyscale picture? For this purpose select B/W-Grey as the colour and use the gamma slider to select the required gamma setting. Apply the gamma setting to the 16 adjustment sliders by clicking on the Set gadget. After leaving the CanonPref program using Use or Save , the gamma function is active. While each of the 16 colour sliders provides 256 levels, this does not necessarily mean you can print 256 shades of each colour. The number of colours or shades printed depends upon the number of colours or shades supported by the dither matrix being used. The Canon installation program installs an ordered dither method with 64 shades as the default dither routine. More information about setting up a dither matrix can be found on page custdit . Push: Pop: ----- Now, say you want to apply a specific gamma function to each primary colour. You could use the same technique for installing the gamma function as described in the example above for every primary colour. But this technique can be a slow process if you have adjusted some sliders by hand. This is why the Push and Pop gadgets have been introduced. Push saves all your current slider settings on to the stack. After changing the colour component you can easily Pop the settings from the stack. Using Pop for every colour component is fast and easy. Load: Save: ----- You can save the your colour adjustment function to a file for later use. You could save your adjustment settings for various kinds of paper, for example, and reload them when needed. Save will cause the system file requester to appear and you can choose a path and filename for saving. Load will cause the file requester to appear and you can choose the file for loading. Note that Save and Load only affect the currently selected colour component. Comp M: Comp Y: ------- The integer gadgets Comp. M and Comp. Y can be used to adjust the ink compensation of the printer driver. Printer inks are not completely pure materials. For example there is some yellow mixed into the magenta ink, and there is some magenta found in the cyan ink. The ink compensation values will correct for these impurities allowing blues, for example, to be printed as blues rather than purples. Comp. M defines the percentage of magenta ink in the cyan ink. Comp. Y defines the percentage of yellow ink in the magenta ink. p. nocomp Canon's custom dither and colour correction routines can be turned off by printing with a Workbench dither method other than ordered , or a density below 3. Because of this, colour adjustment and ink compensation work only with the ordered dither routine set in Workbench preferences and densities above 2. Colour adjustment works with nearly every Amiga application. Application programs with their own colour adjustment routines should not be used with Canon's routines enabled. Programs with their own colour adjustment routines include Art Department Professional's PrefPrinter saver, TruePrint24 and PageStream V2.x (not V3). Use density 1 or 2 when printing with these programs. The CanonsStudio picture-printing program also belongs to this category of programs, but it automatically disables the CanonStudio driver's colour adjustment routines. Use: Cancel: ------- You can leave the window with the Use or Cancel gadget. Changes made to the settings are accepted with Use . Cancel leaves the settings unchanged and any changes made will be lost. Note: Use does not save the changes made to your environment. This is achieved by using the Use or Save gadget in the main window. "Customize Dither..." --------------------- Most printers print pictures using a `binary coding', or to put it more simply: a dot can either be printed, or not. There is no way to control the brightness of a single dot. A monochrome printer can only print one colour: black. Colour printers support the printing of three or four primary colours: cyan, magenta, yellow and black. A special technique is needed for printing more shades. Dither routines provide such a technique. Dither routines print dots of a primary colour in various patterns, creating the impression of different shades, thanks to the fact that the human eye can't distinguish adjacent dots from a distance. Each pixel of a picture produces a pattern of printed dots. The pattern is described by a dither matrix. There are almost no limits to the size of the dither matrix. Workbench dither matrices (ordered and halftone) are of the size 4*4, which is equal to printing 17 shades (A normal 4*4 matrix produces 17 shades. This is not true in case of the Workbench dither matrix). A matrix consists of threshold values. Each matrix value is compared with the picture's pixel value. If the value of the pixel is higher than the matrix value, a dot gets printed. Dither patterns allow you to print a huge number of shades. The number of printable shades mainly depends on the size of the dither matrix used and the quality of the printer. Many printers have problems with inks running or overlapping dots. These problems have a huge influence on the decision as to which dither matrix to use. There is also a strong relationship between a dither matrix and the colour adjustment required. A change of print density often requires a change of the dither matrix and/or colour adjustment, and changing the dither matrix usually requires the colour adjustment also to be changed. Canon gives you the facilities to define the dither matrix used for printing. Many dither matrices are included with the CanonDisk. These are handled in an extra chapter; this chapter covers only the use of the Customize Dither... window. This window allows you to edit the current dither pattern. The theoretical aspects of digital halftoning are complex, and are way beyond the scope of this manual. If you are interested in more detailed information, a very good book can be recommended: Robert Ulichney Digital Halftoning MIT Press ISBN 0-262-21009-6 The book is easy to understand and comes with lots of examples. Most of the dither routines used in the Canon driver are described in detail in this book. Selecting Customize Dither leads you to a window allowing you to select a wanted dither method for color and greyscale printing. A preview of the selected dither method is shown on the right of the window. The color gadget in the upper left corner decides wether the selected dither method is used for greyscale or color printing. Selecting the CUSTOM dither method makes the "Edit Dither" gadget unghosted. Selecting Edit Dither allows you to define and edit a wanted dither method for printing: Load: Save: ----- Using the "Customize Dither..." window is very similar to using the "Color Adjustments..." window. The Load and Save gadgets allow you to load and save the required dither matrix for a particular colour component. Only the currently selected Color component is saved or loaded. Color Push: Pop: ----- Let's assume you want to print a colour picture using the halftone dither. There are two ways you can enable the halftone dither in CanonPref. You can either load the dither matrix from disk for each primary colour, or you can use the stack. The stack can be controlled using the Push and Pop gadgets on the left-hand side of the window. All you have to do to install the required dither matrix is to load the dither. Afterwards click on the Push gadget and the dither is saved on to the stack. Now switch the primary colour and Pop the matrix from the stack. Enable the matrix for all primary colours by using the stack. You can switch between the primary colours by using the Color cycle gadget Color . A Canon dither matrix may be any rectangular shape and can consist of up to 512 values. Up to 64 values can be included on each row (X) or column (Y). You can use the X and Y sliders to define the size of the matrix. The current size of the matrix is shown on the left-hand side of the window. Canon's custom dither routines can be turned off by printing with a Workbench dither method other than ordered, or a density below 3. The custom dither routines work with nearly every Amiga application. Application programs that provide their own dither routines should not be used with Canon's routines enabled. Programs that do not work include Art Department Professional's PrefPrinter saver, TruePrint24 and PageStream V2.x (not V3!). Use density 1 or 2 when printing with these programs. The CanonStudio picture-printing program also belongs to this category of programs, but it automatically disables the Canon driver's dither routines. Dither Routines --------------- Many dithering methods are supplied with the CanonDisk, and these are described below. In each case a larger dither mask size produces a printout which can represent a wider range of colours, but will produce less spatial information per unit area of paper. Conversely, a smaller dither mask size can reproduce fewer colours (or shades) but more closely approximates the true resolution of your printer. Another way of expressing this is simply that there is a tradeoff between printing ``lots'' of colours and printing in high resolution. Given a specific printer with a specific DPI capability, asking for ``lots'' of colours means using a larger dither mask size. A larger dither mask size cuts down on your effective resolution. For instance, using a dither mask of 16*16 on your 360 dpi printer will result in 360/16=22.5 dpi (This values is often described as l/inch (lines per inch) or `screen frequency'.) with full colour information. Note that this can work to your advantage when enlarging a picture. Enlarging means that there are more dots to work with, which offsets the loss in resolution caused by a larger dither mask size. This, added to the benefits to be had by being able to reproduce more colours (or shades), means that your enlarged posters will look quite good. Also note that many printers, including most laser printers and dot-matrix printers, have considerable dot gain problems. For example, a 300 dpi laser printer does not actually print dots which are 1/300 of an inch in size. Rather, its dots will be much larger. This causes some dithers, such as the Floyd-Steinberg and Ordered dithers, to produce intensely over-saturated or `muddy' prints. Other dithers, such as the two halftone dithers, overcome this problem with low-end printers. If you want to learn more about dither routines and digital halftoning, here is a very good book to study: Robert Ulichney Digital Halftoning MIT Press ISBN 0-262-21009-6 The book is easy to understand and comes with lots of examples. Most of the dither routines used by CanonDisk are described in detail in this book. With the exception of the Floyd, Jarvis, Stucki and Blue Noise dithers, all dither routines described below are supported by the Canon printer drivers. OK, now let's discuss the dither routines in detail: The number of printable colours is usually directly related to the size of the dither matrix. Most of the ordered dither routines described below exist in several sizes. You can distinguish between them by their filenames. For instance a filename of "Halftone-A-4" means the Halftone A dither routine for 4 shades; while "Halftone-A-256" means the Halftone A dither routine for 256 shades. Halftone-A - number of colors Halftone-B - number of colors 10 Percent 20 Percent 50 Percent 80 Percent 90 Percent **** ******** ******** * *** **** ***** ** ***** ** *** **** ***** * ***** **** ******** ******** **** ******** ******** ** *** **** **** * ****** * ** *** **** **** * ***** * * **** ******** ******** The halftone dithers (Halftone-A and Halftone-B) differ in how they place a halftone matrix. This is the classic clustered halftone method used by most book publishers, and PostScript (see figure halftonea ). To improve the dither output the halftone matrix is rotated by 45 degrees. Halftone-A causes the halftone matrix for each of the primary colours to be centred about the same point. This means that the primary colours will overlap completely, leaving a lot of white paper showing through. This may be appropriate for some better dye-sublimation type printers, or other colour printers with good registration where the inks mix well. Halftone-B, on the other hand, staggers the halftone matrix of each primary colour so that they do not overlap. This is similar in concept to traditional colour offset printing. Halftone-B may produce better results on printers whose inks do not mix well, and on printers with less than perfect registration. The halftone dithers can produce some extremely good results and compensate for the dot gain problems outlined above. Try both halftone dithers to see which one is better for your particular task. If you are going to photocopy your printouts, using Halftone results in a much better copy. Halftone-B is somewhat different to the other dither matrices. You have a special dither matrix for each colour. Because of this, each dither filename includes the abbreviation of the color (C = cyan, Y = yellow, M = magenta, K = black or greyscale). If you are using Halftone-B with one of the Canon printer drivers, you must increase the brightness of the black colour component by 50 . Use the bright+ gadget in the appropriate Canon driver preferences programs for increasing brightness. Halftone-B is a good example of the relationship between colour adjustment and dither routines. You have to consider both settings.

The halftone dot hexagonal and not rectangular shaped, resulting in a better spatial frequency perrformance. The results of hexagonal cluster are good in color and resolution, making this dither a great deal for many tasks.

The ordered dither is particularly vulnerable to over-saturation due to dot gain in high resolutions. But you will get good output if you don't use the maximum print density of your printer (for instance, by using 180 dpi on a 360 dpi printer). Ordered-B - number of colors 10 Percent 20 Percent 50 Percent 80 Percent 90 Percent * ** ** ** ** ******** ******** ** ** ** ** ** ******** ******** ** ** ** ** ***** ** ** ** ** ** **** *** ** * ** ** ** ******** ******** ** ** ** ** ******** ******** ** ** ****** ****** ** ** ****** ****** This dither is a mixture of a dispersed dither like Ordered and a clustered dither like Halftone. The dither is meant specially for high resolution printers with dot gain problems. For instance, if you print a picture with 360*360 dpi using Ordered-B-64, you get a picture that appears to be printed at 180*180 dpi. But while colours are printed emulating 180 dpi, all the black parts of the picture are printed using 360 dpi. Don't be confused, the printed picture is still better than a picture in real 180 dpi resolution. The Ordered-B dither is especially useful for colour DTP because you can combine good colour pictures with fine high quality text.

Spiral-Dot is such a dither. The spiral-dot dither is essentially half of the classical `screen', with dark squares growing to fill the plane without the alternating light squares. Spiral-Dot looks quiet similar to the Halftone-A matrix, zero degree rotated.

The Line dithers are such dithers. The horizontal (as well as the vertical) dither overcomes many of the dot gain problems that the error diffusion, Blue Noise and Ordered dithers have with low-end printers. These dithers (particularly the diagonal dithers) are especially good for enlarged pictures.

The Brick dithers are such dithers. The Forward-Brick (as well as the Backward-Brick) dither overcomes many of the dot gain problems that the error diffusion, Blue Noise and Ordered dithers have with inexpensive printers. These dithers are especially good for enlarged pictures. Floyd Steinberg (no "char" picture) This is a very popular error diffusion dither method first suggested by Floyd and Steinberg. They argued that a filter with four elements was the smallest number that could produce `good' results. The values were chosen to particularly ensure a checkerboard pattern at the middle grey or shade of colour. This dither method provides a good compromise of speed and quality. The reason for the popularity of this algorithm is clear -- several colour shade levels are represented by pleasingly isotropic, structureless distributions of dots. But there are some shortcomings: * Correlated artifacts in many of the colour shade level patterns. This can be easily seen by printing a greyscale ramp. * Directional hysteresis due to the raster order of processing. This artifact is most apparent in very light and very dark patterns. * Transient behaviour near edges or boundaries. Jarvis, Judice und Ninke In 1976 Jarvis, Judice and Ninke documented an error filter with 12 elements. The large filter size reduces some of the artifacts seen with the 4-element filter of Floyd and Steinberg, but directional hysteresis in the very dark and light regions are increased, and pixels are clustered together more in the middle of colour shade regions. It also sharpens the pictures. Stucki-Dither The Stucki filter provides nearly the same output as the Jarvis filter, though you may notice differences in sharpness. Blue-Noise 30-50% In trying several combinations of deterministic values in a 4-element error filter, none proved better than the famed filter of Floyd and Steinberg. Two variations of this basic filter are the Blue Noise dithers included with the CanonStudio program. Both are processed with serpentine rasters. The serpentine raster used in processing is responsible for much of the directional artifact elimination. The noisy threshold (30% or 50% white noise) breaks up most of the remaining stable texture patterns, yielding good radial symmetry at the expense of adding some low frequency energy. Blue noise is especially useful when printing light shades and fading colours. All error diffusion dithers, including Blue Noise, can produce very good results on colour printers that have little dot gain and very good registration. If it produces a washed-out print or particularly bad patterns, then try another dither (see the custom Ordered-B or Halftone, for instance). BJ-FontShop =========== The BJ-FontShop program enables you to generate and download fonts from your Amiga to the BJ and BJC printers (except for the BJC-8x0, BJ-130, BJ-300 and BJ-330). As a font source it uses standard Amiga fonts. If you use a font with a high resolution (size, that is) you can get the best print quality out of your printer. The printer's dip switches must be set to BJ emulation in order to use downloaded fonts. The BJ-FontShop program only works in combination with the CanonBJ5-230 driver. BJC-600/4000 users must install a driver as if they were Canon BJ-200 users in order to get FontShop and the proper driver installed. "T" char next "T" char ---------------- --------- \ | ---------- | | ---- | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | \ | | | | / font size | | | | | | | | | | Baseline-> |- - - - - - -| | | | | | | | | | | | | | | | | | | ---------------- --- / \_____ _______/ ^ \/ | width ------ InterSpace FontShop can be controlled similarly to the CanonPref programs described above. It has the same font independent user interface and startup arguments. Now you can save the download font by clicking on the Download gadget. The font will be used next time you print using the CanonBJ5-230 driver. MAKE SURE YOUR PRINTER DIP SWITCHES ARE SETUP CORRECTLY FOR DOWNLOAD FONTS. There are several things you can alter in the main window. These are in most cases only for experienced users and will be discussed in the following list of possibilities: Font: This is a readonly field and shows you the currently selected font. CPI: This is a readonly field and shows you the characters per inch (cpi) of the selected font. The cpi number depends on your selected font, font width, InterSpace and font mode (Proportional or Mono Spaced characters). "Select a font..." This gadget will bring up the systems font requester. Select a required font and style (underlined, italics, bold, or invers) for downloading. Note: the printers normal font height is 48 dots (and high 36 dots wide). You may download a smaller or greater fonts, but a font greater than 48 dots will most likely be cut of at the bottom. If you only want to use the upper case characters of a downloaded font, you may use a font heigher than 48 dots with a baseline of up to 48 dots. If all upper case characters are above the baseline, everything should work fine and you get "super" characters. The default baseline of a selected font is shown in the "Baseline" gadget after selecting a font. There are several commercial and public domain font collections available, offering you large 48 dot high fonts in high quality. Also, you may use Intellifonts (CompuGraphic) from Agfa Corporation if you have installed the right diskfont library (see your Kickstart 2 manual for more information). Over 250 Intellifonts are available offering you high quality output at variable sizes and styles. Also, if you wish to make your own downloadable chars or alter existing fonts, there are several nice and easy to use font editors available on the Amiga (public domain and commercial). Ask your dealer for advice. To: This is a cycle gadget. If Prefs (Use) is selected, the font is downloaded directly to ENV: directory. The printer driver will download the saved font the next time you send an aRIN or aRIS command. If you want to save the font permanently instead of temporarily, use Prefs (Save) . This will save the font in the non volatile ENVARC: directory. You may also download the font directly to a file for later use by selecting File . These font files can be quickly downloaded from your application program or batch file in quantities. If File is selected and the download is started, a file requester will ask you for a filename. Note: the font files must be copied to PAR: not PRT: ! Space Mode: This is a cycle gadget. You may download a font to the printer in a fixed width ( Mono Space ) given in the Char Width gadget. Or you may download the font with proportional spaced chars. You may define a special space ( InterSpace ) between two proportional chars giving a lighter font impression. Note, the given mode reflects the downloaded font mode, not the Amiga font mode. You may download a mono spaced Amiga font as a proportional printer font (ie. kerning is used). Even if the downloaded font is mono spaced, the printer regards the font as a proportional spaced font (even though it isn't). After selecting a new font with Select a font... this gadget is altered to the mode of the newly selected font. Char Width: This integer gadget can only be activated, if Mono Space mode is active. With this gadget you may define the width of all characters in dots. After selecting a new font, the value of the gadget will be set to the default width of the selected font. In the event you selected a proportional font, the gadget reflects the width of the widest character of that proportional font. InterSpace: This integer gadget can only be activated, if Proportional mode is active. With this gadget you can define a microspace between downloaded proportionally spaced characters. Baseline: With this integer gadget you specify the number of dots between the baseline and the top border. After selecting a new font, the Baseline will automatically be set to the system baseline of that font. Download: After clicking on this gadget, the downloading is started. Please be patient, the download may take some time. During downloading, all gadgets are ghosted. Quit: Clicking on this gadget (or the Close window gadget) quits the program. General information about BJ-FontShop and points to note: FontShop supports accented characters. Note however that some accents are generated by combining two chars (for instance ø = o + /). When downloading such chars in a small size and proportional mode, there may be slight misalignments (for instance causing a o/ instead of ø). You can avoid such problems by altering the size of the special chars or downloading the font in mono space mode. Although the Amiga has a very large font table, the BJ is not capable of holding so many downloadable characters in its printer memory at once. Because of this, only "commonly used" characters are downloaded to the printer. The few characters not downloaded will be printed in the normal resident font of the printer. The program assumes you have 32KB of download RAM in your printer. If you select a large font, this RAM may not be big enough causing some char definitions to be ignored by the printer (accents are the first chars which are lost in this case, therefore make sure they are actually required) Errors and Fixes ---------------- For experienced computer and printer users, it's a known fact: Everything possible that can go wrong, will go wrong. Especially when it comes to printing and there are many places were one can make mistakes. If you can't solve a problem with Canon drivers, a Report program can be found on the CanonDisk. Report prints all driver and CanonStudio settings to a specified disk. Simply return that disk and any further details or samples to the author. Very often in the past users didn't supply enough information to help us find the cause of the problem. Please, use Report and give us any detail or file you have involved in your problem. Report also performs some further system checks. A requester will appear if there is something wrong with your system. Please make sure that you have this information handy when asking for help. Without the output of Report it is nearly impossible to track down problems, and thus supply solutions. If you find a problem with a Canon printer driver, please send a description which makes it possible to reproduce the problem. For this purpose, you should provide the following information: 1. Which application program are you using, and which version of it? 2. Which Workbench revision are you using? 3. Include a dump of the program, as a file (use the CMD program from the Workbench disk for this) and in printed form also. Note: any report disks or samples are not returned unless requested. Too often, returning a disk would cost more postage in Germany than buying a new disk. Also note: include postage if you want an answer. Par: or Prt:? Data should be sent to the printer only via parallel.device ( par: ) or printer.device ( prt: ), and not both at the same time as this may confuse the printer. Empty pages before dump? BJ users with a cut sheet feeder and BJ emulation (for instance BJ200) should not set a top margin as this causes an empty page to be fed before the actual printing. Some applications can print an empty page BEFORE the first print after the driver was loaded into memory (Personal Paint 6.4). The problem only appears with some applications and only when the driver is set to Extended Emulation (Graphic Only). In these cases you have to accept the first page or simply switch the driver to Epson or BJ emulation. The problem is a result of the application trying to print text before graphics. Red text printed with MultiView and CanonBJ-EC If you get only red/magenta text printed from MultiView: this is not a bug in the driver. It's a bug in MultiView that appears with all Amiga printer drivers supported colored text. One solution is to use a BJ driver after setting the printer to BJ emulation. The BJ driver doesn't support color and thus works fine with MultiView. White graphic dumps In the event that stripes or empty lines appear in graphic dumps check your printer margins (DIP switches, preference settings, settings within the program you use,...). Make sure your printers ink cartridge is full. Also make sure your computer has enough memory. In particular Art Department (TM) Professional 2 users should use the MAXMEM option to make sure the driver does have enough memory for printing or ADPro will simply print trash or empty lines. About 100 kb memory should be available before starting to print! No text dumps? There is one reason causing white pages instead of text dumps. After printing graphics using the BJ 2x0 and BJC Extended Emulation mode (or Graphics Only that is), the printer is unable to print text. You must flush the driver out of memory for printing text again. You can flush the driver by using Avail Flush from CLI or by selecting Use or Save in the CanonPref program. No dump? If the printer device immediately reports an error while trying to print a graphic, check that you have selected the correct Canon printer driver in Workbench preferences. No way for Kickstart 2&3 Your printer doesn't work under Kickstart 2 or 3, while with Kickstart 1.3 it works fine? Check the "on-line" and "out of paper" lines in the printer cable. Make sure they are connected correctly. If your cable is wired correctly then, check the two Amiga port chips named 8520. There have been major changes in Kickstart 2 regarding the use of the port chips. Ask your dealer for help if these tips are too technical for you! Empty pages? Empty pages is a known problem of Amiga printer drivers with page orientated printers (like laser printers). After graphics dumps an empty page is printed. So far there is no 100% cure for this problem. Some application programs don't cause an empty page if you enable the Continuous paper type in preferences. Also, some Canon drivers do have a special feature avoiding empty pages, though, it may not allways work. Printer trouble... Printer trouble... requester? Have a look at the TimeOut setting of the Canon drivers. Setting a longer Timeout can avoid such requesters. Note: clicking on the Resume button continues printing without loss of data. No Formfeed If a page is not ejected, check your paper type preferences. Make sure Single is selected as the paper type. Deluxe Paint users may run into the problem of an endless graphic dump -- the Deluxe Paint print requester won't disappear, and the printer doesn't eject the page. This is a known bug in Deluxe Paint and can be easily cured by a mouse click in the Deluxe Paint print requester. Differences between KS 2 and KS 1.3? After switching from Workbench 1.3 to 2/3 your graphic dumps are of different size? This most likely will happen to users using the DIN A4 paper size. For instance, under Workbench 1.3 you used the Letter size, and after switching to Workbench 2/3 you used the DIN A4 size. Because all Canon drivers support the new paper sizes (DIN A4, A5 ...), you get a different printout under Workbench 2.0/2.1. Simply switch back to the Letter size to get the same result as under Workbench 1.3. Patching drivers There are several programs that allow you to `patch' printer drivers in order to alter specific commands or parameters like the Timeout value. Do not use these programs! Set Aspect doesn't work? This problem will most likely happen to CanonStudio users with pictures saved by Art Department Professional. Clicking on Set Aspect does not set the correct aspect ratio of the image for printing. Usually the width of the image is too small, or the picture is too tall to put it another way. Make sure Art Department Professional saves the correct aspect ratio by using its Set Pixel Aspect operator The dpi values saved by Art Department Professional are imported for the Set Aspect function. To dark pictures? If your graphic dumps are too dark or wrongly coloured, it is most likely caused by the disabled colour adjustment routines of the Canon driver. For more information see the color adjustment section. CanonPref and FontShop doesn't startup? All CanonPref and FontShop programs require at least Kickstart 2.04. They also work fine under Workbench 2.1 and 3. Printing trash? Some printers do have problems when connected to the Amiga with an incorrectly wired cable even though the cable might work fine with some other printers and or computers. When printing, strange graphic characters appear on the output. These characters often only appear under special conditions (graphics only). Note you should not use a cable longer than 1.5 meters! Also, on the BJ 2x0 and BJC800 you can easily confuse the printer by not corretly switching between native (Graphics only) and BJ/Epson emulation. Specialy take care when using the PageStram and Workbench driver at the same time! Printer hangs during aRIN? If your BJ printer immeaditly hangs after starting to print and you have to reset the printer for further printing, you should check, if the printer has a problem with the drivers init commands by sending an aRIN command. On extreamly rare occasions some BJ printer may hang up when initialised and the printer has to be reset manualy to proceed (with an unitialised printer). In this case ask your dealer for further help (it's the ESC-[-K-0-1 command that is causeing the problem). Again note: This problem is extreamly rare and before contacting your dealer, check your printer and computer thoroughly first. Page size is wrong Specialy Canon BJC800 users should note, that the Canon BJC800 printer is a single page printer. The printer does not support non cut sheet paper paper. Because of this you must define a page length! The way this is done depends on what emulation you are useing: In Epson mode the page length can be defined by setting CanonForm to ON and defining the number of lines per page in preferences as 250 or the real page length. Setting page length to 250 is recommended. In this case the printer driver itself chooses the optimal page length for your selected paper size. For instance if you select DIN A4 and a page length of 250 lines, the driver automaticly chooses 65 lines per page at 6 lines per inch. Note: the Canon BJ-EC Epson emulation stores the page length in inches. Because of this, small changes to the page length might not affect the output. In Canon Extended Emulation mode, the driver automaticly sets the page length similar to the Epson modes "250" lines mode. In Canon Extended Emulation mode, the printer is also able to print on a greater area. Also the page length can be defined in 1/10" accuracy. Again: use the Canon BJC Extended emulation for graphic prints. Note: setting paper size to FANFOLD (or continues) automaticly defines the maximum page length of 22 inch under Canon Extended Emulation. Altered print height? In case the print height is altered everytime you select a picture in CanonStudio, check your ADJUST ON STARTUP setting in the menu of the smaller main window. Glossary ======== Default: A value used in place of a user-selected value. A factory default is a value programmed into the device at the factory; this value is stored in read-only memory (ROM) and cannot be changed by a user or operator. A user default is a default that is selectable via the control panel. Dot: A dot is the smallest thing a printer can print. The number of dots printed per inch is referred to as the printer's resolution (dpi). Download: The process of transferring soft fonts, macros or raster data from a host computer to the printer's user memory is called downloading. DPI See Dot. ENV: ENVARC: The Amiga operating system and the Canon drivers store their environment settings in two special directories named ENV: and ENVARC: . Settings saved in ENV: are only for temporary usage and are lost when turning the computer off. Parallel I/O An input/output interface that transmits more than one bit of information simultaneously. Centronics is an industry-wide standard form of a parallel interface. Pitch: Pitch describes the number of characters printed in a horizontal inch. Pitch only applies to fixed-spaced fonts since the number of characters per inch varies for proportionally-spaced fonts. See Spacing. Printable Area The printable area is the area of the physical page on which the printer is able to place a dot, wheras the physical page refers to the actual size of the paper installed in the printer. Raster Graphics Images composed of groups of dots are called raster images. Spacing Fonts have either fixed or proportional spacing. Fixed-spaced fonts are those for which the inter-character spacing is constant. Proportionally-spaced fonts are those for which the inter-character spacing varies with the natural shape of a character. Symbol Set A symbol set is a unique ordering of the characters in a font. Each symbol set is defined with a unique set of applications in mind. Symbol sets are created for many purposes. Typeface Typeface is a generic name for graphics symbols having common design features. Each typeface has unique and distinguishing characteristics. (Continue by pressing 'Q')
