printer.device/CMD_WRITE printer.device/CMD_WRITE
NAME
CMD_WRITE -- 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 CMD_WRITE succeeded, then io_Error will be zero.
Otherwise io_Error will be non-zero.

printer.device/PRD_DUMPRPORT printer.device/PRD_DUMPRPORT
NAME
PRD_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).
If you are running under version 36, or greater
of graphics.library, it is recommended that
you fill in "io_Modes" with the ULONG (32-bit)
value returned from calling:
ULONG ModeID = GetVPModeID(struct ViewPort *);
Doing so provides for upwards compatability with
the new display modes available under V36
(example: aspect ratio calculations for new
display modes).
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 following:
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 opened 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 opened...
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 requester),
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 requester
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 have been warned).

2. Use Black ribbon for non-color dumps; Color ribbon for color dumps.
3. Linefeeds # of vertical dots printed.
4. Densities 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. Densities 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).

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 will probably need to drop down to 16 pins.

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 V1.3 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. Densities 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. Keypad menu option 3b COLOR ADJUSTMENT may be set from the keypad.
For normal prints this option should be set to "do not adjust".
5. Keypad menu option 3d VIDEO COLOR CORRECTION may be set from the keypad.
For normal prints this option should be set to "do not adjust".
6. Keypad menu option 5 BACKGROUND COLOR EXCHANGE may be set from the
keypad. For normal prints this option should be set to "print colors
as received".
7. Once a picture has been printed additional copies may be printed
without resending by using the printers keypad.
8. This driver is not on the V1.3 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 V1.3 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)

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/PRD_PRTCOMMAND printer.device/PRD_PRTCOMMAND
NAME
PRD_PRTCOMMAND -- send a command to the printer
FUNCTION
This function sends a command to either the parallel or serial
device. 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.
IO REQUEST IOPrtCmdReq
io_Message mn_ReplyPort set
io_Device preset by OpenDevice
io_Unit preset by OpenDevice
io_Command PRD_PRTCOMMAND
io_PrtCommand the actual command number
io_Parm0 parameter for the command
io_Parm1 parameter for the command
io_Parm2 parameter for the command
io_Parm3 parameter for the command
RESULTS
Errors: if the PRD_PRTCOMMAND succeeded, then io_Error will be zero.
Otherwise io_Error will be non-zero. An error of -1 indicates that
the command is not supported by the current printer driver. This
could be used to check if the connected printer supports a particular
command (italics for example).

printer.device/PRD_QUERY printer.device/PRD_QUERY
NAME
PRD_QUERY -- query printer port/line status
FUNCTION
This command returns the status of the printer port's lines and
registers. Since the printer port uses either the serial or
parallel port for i/o, the actual status returned is either the
serial or parallel port's status.

printer.device/PWrite printer.device/PWrite
NAME
PWrite -- internal write to printer port
SYNOPSIS
error = (*PrinterData->pd_PWrite)(buffer, length);
D0 A0 D0
FUNCTION
PWrite writes 'length' bytes directly to the printer. This
function is generally called by printer drivers to send
their buffer(s) to the printer.
This function is accessed by referencing off the PrinterData (PD)
structure. Below is a code fragment to show how to do get access
to a pointer to the PrinterData (PD) structure.
#include <exec/types.h>
#include <devices/printer.h>
#include <devices/prtbase.h>
struct IODRPReq PReq;
struct PrinterData *PD;
struct PrinterExtendedData *PED;
/* open the printer device (any version); if it opened... */
if (OpenDevice("printer.device", 0, &PReq, 0) == NULL) {
/* get pointer to printer data structure */
PD = (struct PrinterData *)PReq.io_Device;
/* write something directly to the printer */
(*PD->pd_PWrite)("Hello world\n", 12);
CloseDevice(&PReq); /* close the printer device */
}
