|
;* File Printer Port Driver
|
|
;*
|
|
;*
|
|
;* Description:
|
|
;* The goal of this GS port driver is to allow the user of any printer
|
|
;* driver to save their printer driver output in a user specified file.
|
|
;*
|
|
;* The user interface includes a standard file dialog box of where to
|
|
;* save the printer driver output.
|
|
;*
|
|
;* If this port driver encounters any error, a dialog box will be
|
|
;* displayed with the error code and a message saying that the printer
|
|
;* output could not be saved. The user will have two buttons -
|
|
;* DELETE_OUTPUT and OK. Delete output will simply delete the output
|
|
;* file and act as an OK button.
|
|
;*
|
|
;* Rational for this driver: I want to be able to 'print' a file on
|
|
;* my GS, bring the file to work and print the file on a printer here.
|
|
;* (An additional utility (hopefully a CDEV) will do the inverse of
|
|
;* what this driver does - it will put up a dialog box to get the user
|
|
;* to select a printer data file to to printed. Lets get this to work
|
|
;* first).
|
|
;*
|
|
;*
|
|
;* Notes:
|
|
;* This printer port driver is complies to the version 3.0 printer
|
|
;* driver specs. See IIGS technotes 35 (dated March 1990) and
|
|
;* technote 36 (dated September 1989) for the printer/port driver
|
|
;* specificiations.
|
|
;*
|
|
;* The resulting port driver must be given filetype $BB
|
|
;* auxiliary type $02 (IE: Port driver for local printer).
|
|
;*
|
|
;* The entire file port driver is designed to fit within one 64K
|
|
;* segment/bank of memory. If it must span more than one memory
|
|
;* bank, then you will have to correct the dispatch routine and
|
|
;* possibly some references to the internal data structures.

|
|
;* History: Nov 11 1990 Dave Began coding this port driver.
|
|
;* (started with IIGS technotes 35 & 36)
|
|
;*
|
|
;* Jan 19 1991 Dave Got this code compiled and attempted
|
|
;* the first couple of tests... results
|
|
;* are that the calling convention isn't
|
|
;* what I expected (Orca/C...) - technote
|
|
;* #35 confirmed my guess... time for
|
|
;* some macros to replace csubroutine &
|
|
;* creturn.
|
|
;*
|
|
;* Jan 20 1991 Dave Changed all routines to use the new
|
|
;* set of port_subroutine/return/complete
|
|
;* macros.
|
|
;* Now its time to check the macros and
|
|
;* after that try the driver again...
|
|
;*
|
|
;* Jan 21 1991 Dave Changed return macro to include the
|
|
;* completion routine - this was after
|
|
;* hours of looking at the 'Printer' port
|
|
;* driver.
|
|
;*
|
|
;* This revision caused 'Printer
|
|
;* Communication Error's from the
|
|
;* Imagewriter printer driver.
|
|
;*
|
|
;* The epson printer driver was happy...
|
|
;*
|
|
;* Jan 31 1991 Dave After a trip into the Orca/Disassembler
|
|
;* to peek into the port drivers from
|
|
;* Bill Heinman to see the return procedure
|
|
;* from all the entry points, now we have
|
|
;* another port_return macro (named
|
|
;* port_return2).
|
|
;*
|
|
;* Another 'Printer Communication Error'...
|
|
;*
|
|
;* Feb 3 1991 Dave Well... that didn't work out too well.
|
|
;* Besides, I didn't really like the second
|
|
;* return macro.
|
|
;*
|
|
;* The second macro is gone now and I've
|
|
;* changed the return macro so that it now
|
|
;* JSL's to the completion routine and
|
|
;* the RTL was removed from the macro.
|
|
;* This allows me to add the CMP #1 for
|
|
;* the routines that need it (like lots
|
|
;* of them, but not all of them...) and
|
|
;* then you have to pop an RTL in the code.
|
|
;*
|
|
;* With these changes, I have gotten the
|
|
;* Imagewriter driver to complete (and
|
|
;* now I have to test the rest, once I
|
|
;* finish with the comments here and in
|
|
;* the macro source...)
|
|
;*
|
|
;* This version works correctly with the
|
|
;* Imagewriter and Epson printer drivers.
|
|
;* The Imagewriter LQ driver returns a
|
|
;* 'Printer not Imagewriter LQ, not ready
|
|
;* or out of paper.' (cancel) dialog.
|
|
;* The Laserwriter (renamed) creates a
|
|
;* blank dialog box (no message) then hangs.
|
|
;*
|
|
;* Feb 3 1991 Dave I added the calls to the completion
|
|
;* routines for the async_read & write
|
|
;* background calls and a set of counters
|
|
;* for each port call.
|
|
;*
|
|
;* Results same as before...
|
|
;*
|
|
;* Feb 12 1991 Dave Well, after debugging to find out that
|
|
;* the ImageWriter LQ problem is related
|
|
;* to the information read from the printer
|
|
;* it was time to disassemble the code until
|
|
;* I found out what we can do about it.
|
|
;*
|
|
;* The IWLQ driver puts up the status dialog
|
|
;* after the following calls:
|
|
;* Open (no problem here)
|
|
;* Write
|
|
;* 6 bytes ($1b,$5a,$00,$02,$1b,$3f)
|
|
;* Read
|
|
;* 8 bytes (we returned zero)
|
|
;* Write
|
|
;* 8 bytes (All $ff...)
|
|
;* Status
|
|
;* Bits checked $87 - one at a time
|
|
;* Close (no problem here)
|
|
;*
|
|
;* Now after disassembling the IWLQ
|
|
;* driver, I found that the string to
|
|
;* return on the Read is as follows:
|
|
;* 5 to 8 bytes returned
|
|
;* string: $4c,$51,$31,<don't care>,
|
|
;* $XX,$XX,$XX
|
|
;* Where XX will cause a bit to get set:
|
|
;* $45 - bit $4 Multiple bins
|
|
;* $46 - bit $4 Multiple bins
|
|
;* $43 - bit $2 Color
|
|
;*
|
|
;* I've added this...
|
|
;*
|
|
;* Feb 13 1991 Dave Problem is that the same dialog came
|
|
;* up - after some debugging I found that
|
|
;* we are returning the bytes in the
|
|
;* wrong order (I fixed them to see it
|
|
;* work!)
|
|
;*
|
|
;* I tried the beta version of the DeskJet
|
|
;* printer drivers and they worked like a
|
|
;* charm!
|
|
;*
|
|
;*
|
|
;* Since I got the ImWr LQ printer driver
|
|
;* to work, it seemed like a good time to
|
|
;* generalize the printer identification
|
|
;* routines. I've also defined what to
|
|
;* expect/return from/to the ImageWriter LQ
|
|
;* and the ImageWriter printer drivers.
|
|
;*
|
|
;*
|
|
;* At this point in time the NULL port
|
|
;* driver is complete (YA HOO!)!!!
