TABLE OF CONTENTS printer.device/DumpRPort printer.device/Flush printer.device/Invalid printer.device/PrtCommand printer.device/PWrite printer.device/Query printer.device/RawWrite printer.device/Reset printer.device/Start printer.device/Stop printer.device/Write printer.device/DumpRPort printer.device/DumpRPort NAME DumpRPort - dump the specified RastPort to a graphics printer. FUNCTION Print a rendition of the supplied RastPort, using the supplied ColorMap, position and scaling information, as specified in the printer preferences. IO REQUEST io_Message mn_ReplyPort set if quick I/O is not possible. io_Command PRD_DUMPRPORT. io_Flags IOB_QUICK set if quick I/O is possible. io_RastPort ptr to a RastPort. io_ColorMap ptr to a ColorMap. io_Modes the 'modes' flag from a ViewPort structure, (the upper word is reserved and should be zero). io_SrcX x offset into the RastPort to start printing from. io_SrcY y offset into the RastPort to start printing from. io_SrcWidth width of the RastPort to print (from io_SrcX). io_SrcHeight height of the RastPort to print (from io_SrcY). io_DestCols width of the printout in printer pixels. io_DestRows height of the printout in printer pixels. io_Special flag bits (some of which pertain to DestCols and DestRows). -if SPECIAL_MIL is set, then the associated parameter is specified in thousandths of an inch on the printer. ie. if DestCols = 8000, DestRows = 10500 and SPECIAL_MILROWS and SPECIAL_MILCOLS is set then the printout would be 8.000 x 10.500 inches. -if SPECIAL_FULL is set, then the specific dimension is set to the maximum possible as determined by the printer limits or the configuration limits; whichever is less. -if SPECIAL_FRAC is set, the parameter is taken to be a longword binary fraction of the maximum for that dimension. -if all bits for a dimension are clear, (ie. SPECIAL MIL/FULL/FRAC and ASPECT are NOT set) then the parameter is specified in printer pixels. -if SPECIAL_CENTER is set then the image will be put between the left and right edge of the paper. -if SPECIAL_ASPECT is set, one of the dimensions may be reduced/expanded to preserve the aspect ratio of the print. -SPECIAL_DENSITY(1-7) this allows for a maximum of 7 different print densities. DENSITY1 is the lowest density and the default. -SPECIAL_NOFORMFEED - this allows for the mixing of text and graphics or multiple graphic dumps on page oriented printers (usually laser jet printers). When this flag is set the page will not be ejected after a graphic dump. If you perform another graphic dump without this flag set OR close the printer after printing text after a graphic dump, the page will be ejected. -if SPECIAL_TRUSTME is set then the printer specific driver is instructed to not issue a reset command before and after the dump. If this flag is NOT checked by the printer specific driver then setting this flag has no effect. Since we now recommend that printer driver writers no longer issue a reset command it is probably a safe idea to always set this flag when calling for a dump. -if SPECIAL_NOPRINT is set then the following is done: Compute print size, set 'io_DestCols' and 'io_DestRows' in the calling program's 'IODRPReq' structure and exit, DON'T PRINT. This allows the calling program to see what the final print size would be in printer pixels. Note that it modifies the 'io_DestCols' and 'io_DestRows' fields of your 'IODRPReq' structure. It also sets the print density and updates the 'MaxXDots', 'MaxYDots', 'XDotsInch', and 'YDotsInch' fields of the 'PrinterExtendedData' structure. There following rules for the interpretation of io_DestRows and io_DestCols that may produce unexpected results when they are not greater than zero and io_Special is zero. They have been retained for compatability. The user will not trigger these other rules with well formed usage of io_Special. When io_Special is equal to 0, the following rules (from the V1.1 printer.device, and retained for compatibility reasons) take effect. Remember, these special rules are for io_DestRows and io_DestCols and only take effect if io_Special is 0). a) DestCols>0 & DestRows>0 - use as absolute values. ie. DestCols=320 & DestRows=200 means that the picture will appear on the printer as 320x200 dots. b) DestCols=0 & DestRows>0 - use the printers maximum number of columns and print DestRows lines. ie. if DestCols=0 and DestRows=200 than the picture will appear on the printer as wide as it can be and 200 dots high. c) DestCols=0 & DestRows=0 - same as above except the driver determines the proper number of lines to print based on the aspect ratio of the printer. ie. This results in the largest picture possible that is not distorted or inverted. Note: As of this writing, this is the call made by such program as DeluxePaint, GraphicCraft, and AegisImages. d) DestCols>0 &DestRows=0 - use the specified width and the driver determines the proper number of lines to print based on the aspect ratio of the printer. ie. if you desire a picture that is 500 pixels wide and aspect ratio correct, use DestCols=500 and DestRows=0. e) DestCols<0 or DestRows>0 - the final picture is either a reduction or expansion based on the fraction |DestCols| / DestRows in the proper aspect ratio. Some examples: 1) if DestCols=-2 & DestRows=1 then the printed picture will be 2x the AMIGA picture and in the proper aspect ratio. (2x is derived from |-2| / 1 which gives 2.0) 2) if DestCols=-1 & DestRows=2 then the printed picture will will be 1/2x the AMIGA picture in the proper aspect ratio. (1/2x is derived from |-1| / 2 which gives 0.5) NOTES The printer selected in preferences must have graphics capability to use this command. The error 'PDERR_NOTGRAPHICS' is returned if the printer can not print graphics. Color printers may not be able to print black and white or greyscale pictures -- specifically, the Okimate 20 cannot print these with a color ribbon: you must use a black ribbon instead. If the printer has an input buffer option, use it. If the printer can be uni or bi directional, select uni-directional; this produces a much cleaner picture. Most printer drivers will attempt to set unidirectional printing if it is possible under software control. Please note that the width and height of the printable area on the printer is in terms of pixels and bounded by the folllowing: a) WIDTH = (RIGHT_MARGIN - LEFT_MARGIN + 1) / CHARACTERS_PER_INCH b) HEIGHT = LENGTH / LINES_PER_INCH Margins are set by preferences. For BGR printer support, the YMC values in the printer specific render.c functions equate to BGR respectively, ie. yellow is blue, magenta is green, and cyan is red. Data Structures --------------- The printer specific and non-specific data structures can be read ONCE you have opended the printer device. Here is a code fragment to illustrate how to do just that. #include <exec/types.h> #include <devices/printer.h> #include <devices/prtbase.h> #include <devices/prtgfx.h> struct IODRPReq PReq; struct PrinterData *PD; struct PrinterExtendedData *PED; open the printer device / if it opended... if (OpenDevice("printer.device", 0, &PReq, 0) == NULL) { get pointer to printer data PD = (struct PrinterData *)PReq.io_Device; get pointer to printer extended data PED = &PD->pd_SegmentData->ps_PED; let's see what's there printf("PrinterName = '%s', Version=%u, Revision=%u\n", PED->ped_PrinterName, PD->pd_SegmentData->ps_Version, PD->pd_SegmentData->ps_Revision,); printf("PrinterClass=%u, ColorClass=%u\n", PED->ped_PrinterClass, PED->ped_ColorClass); printf("MaxColumns=%u, NumCharSets=%u, NumRows=%u\n", PED->ped_MaxColumns, PED->ped_NumCharSets, PED->ped_NumRows); printf("MaxXDots=%lu, MaxYDots=%lu, XDotsInch=%u, YDotsInch=%u\n", PED->ped_MaxXDots, PED->ped_MaxYDots, PED->ped_XDotsInch, PED->ped_YDotsInch); CloseDevice(&PReq); } Preferences ----------- If you want the user to be able to access the printer preferences items without having to run preferences (like DPAINT II's printer requestor), here is what you do. You can look at the printer's copy of preferences by referring to 'PD->pd_Preferences' (the printer device MUST already be opened at this point). After you have this you could put up a requestor and allow the user to change whatever parameters they wanted. BEAR IN MIND THAT YOU ARE RESPONSIBLE FOR RANGE CHECKING THESE SELECTIONS! Listed below are the printer preferences items and their valid values. PrintPitch - PICA, ELITE, FINE. PrintQuality - DRAFT, LETTER. PrintSpacing - SIX_LPI, EIGHT_LPI. PrintLeftMargin - 1 to PrintRightMargin. PrintRightMargin - PrintLeftMargin to 999. PaperLength - 1 to 999. PrintImage - IMAGE_POSITIVE, IMAGE_NEGATIVE. PrintAspect - ASPECT_HORIZ, ASPECT_VERT. PrintShade - SHADE_BW, SHADE_GREYSCALE, SHADE_COLOR. PrintThreshold - 1 to 15. PrintFlags - CORRECT_RED, CORRECT_GREEN, CORRECT_BLUE, CENTER_IMAGE, IGNORE_DIMENSIONS, BOUNDED_DIMENSIONS, ABSOLUTE_DIMENSIONS, PIXEL_DIMENSIONS, MULTIPLY_DIMENSIONS, INTEGER_SCALING, ORDERED_DITHERING, HALFTONE_DITHERING. FLOYD_DITHERING, ANTI_ALIAS, GREY_SCALE2 PrintMaxWidth - 0 to 65535. PrintMaxHeight - 0 to 65535. PrintDensity - 1 to 7. PrintXOffset - 0 to 255. Asynchronous I/O ---------------- The recommended way to do asynchronous i/o is... a) To send requests for i/o. struct IORequest *ioreq; struct MsgPort *port; UBYTE signal; port = ioreq->io_Message.mn_ReplyPort; signal = port->mp_SigBit; SendIO(ioreq); send request Wait(signal); wait for completion (go to sleep) while ((Msg = GetMsg(port)) != NULL) { get ALL messages } b) To abort a previous request for i/o. struct IORequest *ioreq; AbortIO(ioreq); abort request WaitIO(ioreq); wait for reply at this point you can re-use 'ioreq'. Note that in the above examples 'ioreq' could be any one of... a) struct IOStdReq a standard i/o request b) struct IODRPReq a dumprport i/o request c) struct IOPrtCmdReq a printer command i/o request It is recommend that you do asynchronous i/o in your programs and give the user a way of aborting all requests. V1.3 Printer Driver Notes ------------------------- In general densities which use more than one pass should only be used for B&W shade dumps. They can be used for Grey-Scale or Color Shade dumps BUT the output may tend to look muddy or dark. Also multiple pass Color dumps tend to dirty or smear the ribbon (ie. yellow will get contaminated with the other colors on the ribbon; you've been warned). Alphacom_AlphaPro_101 --------------------- 1. Daisywheel printer (text only). Brother_HR-15XL --------------- 1. Daisywheel printer (text only). CalComp_ColorMaster ------------------- 1. Thermal transfer b&w/color printer (text and graphics). 2. Use Black ribbon for non-color dumps; Color ribbon for color dumps. 3. Linefeeds # of vertical dots printed. 4. Densitie(s) supported are 203x200(1) dpi. 5. This is a dual printer driver. Select a PaperSize of 'Narrow Tractor' for use with the ColorMaster; 'Wide Tractor' for use with the ColorView-5912 (which uses 11 x 17 inch paper). CalComp_ColorMaster2 ------------------- 1. Thermal transfer b&w/color printer (text and graphics). 2. Use Black ribbon for non-color dumps; Color ribbon for color dumps. 3. Linefeeds # of vertical dots printed. 4. Densitie(s) supported are 203x200(1) dpi. 5. This is a dual printer driver. Select a PaperSize of 'Narrow Tractor' for use with the ColorMaster; 'Wide Tractor' for use with the ColorView-5912 (which uses 11 x 17 inch paper). 6. This driver is the same as the Calcomp_ColorMaster driver EXCEPT it is approximately 2 times faster (during color dumps) and requires LOTS of memory (up to 1,272,003 bytes for a full 8 x 10 inch (1600 x 2000 dot) color dump). Typically full-size (color) dumps are 1600 x 1149 dots and require 730,767 bytes. Memory requirements for the ColorView-5912 are up to 2,572,803 bytes for a full 10 x 16 inch (2048 x 3200 dot) color dump. Typically full-size (color) dumps are 2048 x 2155 dots and require 1,732,623 bytes. The memory requirements are 1/3 when doing a non-color printout (on both the ColorMaster and ColorView). Canon_PJ-1080A -------------- 1. Ink jet b&w/color printer (text and graphics). 2. Linefeeds # of vertical dots printed. 3. Densitie(s) supported are 83x84(1) dpi. CBM_MPS1000 ----------- 1. Dot matrix b&w printer (text and graphics). 2. Linefeeds # of vertical dots printed (-1/3 dot if PaperType = Single). *2 3.

Daisywheel printer (text only). Diablo_Advantage_D25 -------------------- 1. Daisywheel printer (text only). Diablo_C-150 ------------ 1. Ink jet b&w/color printer (text and graphics). 2. Always linefeeds 4 dots (limitation of printer). 3. A PaperSize of 'Wide Tractor' selects a maximum print width of 8.5 inches (for wide roll paper). 5. Densitie(s) supported are 120x120(1) dpi. EpsonQ (24-pin Epson compatible) ------ 1. Dot matrix b&w/color printer (text and graphics). 2. Drives all EpsonQ (LQ1500, LQ2500, etc.) compatible printers. 3. Linefeeds # of vertical dots printed. 4. Density XDPI YDPI XYDPI Comments 1 90 180 16200 2 120 180 21600 3 180 180 32400 4 360 180 64800 *1 5,6,7 same as 4 5. A PaperSize of 'Wide Tractor' selects a maximum print width of 13.6 inches (for wide carriage printers). 6. A PaperType of 'Single' uses only 16 of the 24 pins, whereas a PaperType of 'Fanfold' uses all 24 pins. The 'Single' option is useful for those printers which have a weak power supply and cannot drive all 24 pins continuously. If during a single pass of the print head you notice that the top two thirds of the graphics are darker than the bottom one third then you'll probably need to drop down to 16 pins. EpsonX[CBM_MPS-1250] (8/9-pin Epson compatible) -------------------- 1. Dot matrix b&w/color printer (text and graphics). 2. Drives all EpsonX (EX/FX/JX/LX/MX/RX, etc.) compatible printers. 3. Linefeeds # of vertical dots printed (-1/3 dot if PaperType = Single). *2 4.

A PaperSize of 'Wide Tractor' selects a maximum print width of 13.6 inches (for wide carriage printers). Okimate-20 ---------- 1. Thermal transfer b&w/color printer (text and graphics). 2. Use Black ribbon for non-color dumps; Color ribbon for color dumps. 3. Linefeeds an even # of dots printed. (ie. if 3 printed, 4 advanced). 4. Densitie(s) supported are 120x144(1) dpi. Quadram_QuadJet --------------- 1. Ink jet b&w/color printer (text and graphics). 2. Linefeeds # of vertical dots printed. 3. Densitie(s) supported are 83x84(1) dpi. Qume_LetterPro_20 ----------------- 1. Daisywheel printer (text only). Seiko_5300 ---------- 1. Thermal transfer b&w/color printer (graphics only). 2. Use Black ribbon for non-color dumps; Color ribbon for color dumps. 3.

This driver is not on the Workbench or Extras disk. It is available on BIX and directly from Seiko. Seiko_5300a ----------- 1. Thermal transfer b&w/color printer (graphics only). 2. Use Black ribbon for non-color dumps; Color ribbon for color dumps. 3. Density XDPI YDPI XYDPI Comments 1 152 152 23104 drives CH-5301 printer 2 203 203 41209 drives CH-5312 printer 3 240 240 57600 drives CH-5303 printer 4, 5,6,7 same as 3 You must select the proper density to drive the specific printer that you have. 4. This driver is the same as the Seiko_5300 driver EXCEPT it is approximately 2 times faster (during color dumps) and requires LOTS of memory (up to 1,564,569 bytes for a full 8 x 10 inch (1927 x 2173 dot) color dump). Typically full-size (color) dumps are 1927 x 1248 dots and require 898,569 bytes. The memory requirements are 1/3 when doing a non-color printout. 5. This driver is not on the Workbench or Extras disk. It is available on BIX and directly from Seiko. Tektronix_4693D ---------------- 1. Thermal transfer b&w/color printer (graphics only). 2. Densitie(s) supported are 300x300(1) dpi 3. Due to the way the printer images a picture none of the printer preferences options affect the printout with the following exceptions: a)Aspect - Horizontal, Vertical b)Shade - B&W, Grey_Scale, Color ...as a result of this only full size pictures can be printed. 4. This driver is not on the Workbench or Extras disk. It is available on BIX and directly from Tektronix. Tektronix_4696 -------------- 1. Ink jet b&w/color printer (text and graphics). 2. Always linefeeds 4 dots (limitation of printer). 3. Densities supported are 121x120(1), 242x120(black)(2) and 242x120(color)(3). Selecting a density of 2 or higher really doesn't give you true 242 dpi resolution since the printer only has 121 x dots per inch. Instead this mode tells the printer to go into it's double pass mode. Here, it outputs a line of dots at 121 dpi; and outputs the line again (shifted to the right by 1/242 of an inch). This produces much more vibrate colors and gives the illusion of more resolution. One drawback is that large areas of solid colors (red, green, and blue specifically) tend to over-saturate the paper with ink. Density1 outputs all colors in one pass. Density 2 does a double pass on black. Density 3 does a double pass on all colors. Density 1 to 3 correspond to the printer's graphics printing modes 1 to 3 (respectively). 4. This driver is not on the Workbench or Extras disk. It is available on BIX and directly from Tektronix. 5. A PaperSize of 'Wide Tractor' selects a maximum print width of 9.0 inches (for wide roll paper). Toshiba_P351C (24-pin Toshiba compatible) ------------- 1. Dot matrix b&w/color printer (text and graphics). 2. Drives all Toshiba_P351C compatible printers. 3. Linefeeds # of vertical dots printed. 4. Density XDPI YDPI XYDPI Comments 1 180 180 32400 2 360 180 64800 3,4,5,6,7 same as 2 5. A PaperSize of 'Wide Tractor' selects a maximum print width of 13.5 inches (for wide carriage printers). Toshiba_P351SX (24-pin Toshiba compatible) -------------- 1. Dot matrix b&w/color printer (text and graphics). 2. Drives all Toshiba_P351SX (321SL, 321SLC, 341SL) compatible printers. 3. Linefeeds # of vertical dots printed. 4. Density XDPI YDPI XYDPI Comments 1 180 180 32400 2 360 180 64800 3 180 360 64800 two pass 4 360 360 129600 two pass 5,6,7 same as 4 5. A PaperSize of 'Wide Tractor' selects a maximum print width of 13.5 inches (for wide carriage printers). Xerox_4020 ---------- 1. Ink jet b&w/color printer (text and graphics). 2. Always linefeeds 4 dots (limitation of printer). 3. This driver is IDENTICAL to the Diablo_C-150 driver EXCEPT it outputs all black dots TWICE. This is a special feature of this printer and produces much more solid, darker black shades. Please note that some printing time overhead results from this feature; if you don't want it use the Diablo_C-150 driver. 4. Densities supported are 121x120(1) and 242x240(2) dpi. Selecting a density of 2 or higher really doesn't give you true 240 dpi resolution since the Xerox_4020 only has 121 x dots per inch. Instead this mode tells the printer to go into it's pseudo 240 dpi mode. Here, it outputs a line of dots at 121 dpi; moves the paper up 1/240 of an inch and outputs the line again (shifted to the right by 1/240 of an inch). This produces much more vibrate colors and gives the illusion of more resolution. One drawback is that large areas of solid colors (red, green, and blue specifically) tend to over-saturate the paper with ink. 5. A PaperSize of 'Wide Tractor' selects a maximum print width of 9.0 inches (for wide roll paper). Notes ----- *0 - on most printers friction fed paper tends to produce better looking (ie. less horizontal banding) graphic dumps than tractor fed paper. *1 - in this mode the printer cannot print two consecutive dots in a row. It is recommended that you only use this density for B&W Shade dumps. *2 - only when 72 YDPI is selected. This option is useful if you notice tiny white horizontal strips in your printout. *3 - only when 144 YDPI is selected. This option is useful if you notice tiny white horizontal strips in your printout. printer.device/Flush printer.device/Flush NAME Flush - abort all I/O requests (immediate) FUNCTION Flush aborts all stopped I/O at the unit.

The printer device maps this command to the control code set of the current printer. The commands supported can be found with the printer.device/Write command. All printers may not support all functions.

The only commands that will be subsequently allowed to be performed are immediate I/O requests, which include those to start, flush, and finish the I/O after the stop command. IO REQUEST io_Message mn_ReplyPort set if quick I/O is not possible io_Device preset by the call to OpenDevice io_Command CMD_STOP io_Flags IOB_QUICK set if quick I/O is possible printer.device/Write printer.device/Write NAME PCWrite -- send output to the printer FUNCTION This function causes a buffer of characters to be written to the current printer port (usually parallel or serial). The number of characters is specified in io_Length, unless -1 is used, in which case output is sent until a 0x00 is encountered. The Printer device, like the Console device, maps ANSI X3.64 style 7-bit printer control codes to the control code set of the current printer. The ANSI codes supported can be found below. NOTES Not all printers will support all functions. In particular you may not assume that the MARGINS or TABS can be set. Close to half the supported printers don't fully implement one or the other. If you want the features of margins or tabs you will need to fake it internally by sending out spaces. Note that the printer device may have already sent out a "set margins" command to the printer. If you are faking your own margins, be sure to cancel the old ones first. (use the "aCAM" command) Defaults are set up so that if a normal AmigaDOS text file is sent to PRT:, it has the greatest chance of working. (AmigaDOS text files are defined as follows:) tabs - every 8 CR (0x0D) - moves to start of current line LF (0x0A) - moves to start of next line IO REQUEST io_Message mn_ReplyPort set io_Device preset by OpenDevice io_Unit preset by OpenDevice io_Command CMD_WRITE io_Length number of characters to process, or if -1, process until 0x00 encountered io_Data pointer to block of data to process RESULTS io_Error : if PCWrite succeeded, then io_Error will be zero.
