[comp.sys.mac.programmer] seeking info on print drivers

eric@regulus.cs.unc.edu (Eric Grant) (06/14/91)

I need to write a chooser-level print driver for a Lasertechnics grey-scale
printer with a SCSI interface.  I've looked in Inside Mac - there's lots of
information about how applications should use the Print Manager, but very
little information about how to write a print driver.

The printer itself has a limited command set - I expect the Mac will do
all quickdraw to bitmap conversions, much like the drivers for the IISC
and Personal Laserwriter SC.

Obviously the easiest way to proceed is to obtain an existing print driver
and modify it to work with my printer.  I'm seeking information about 
source code to drivers that may be available - both public domain and
commercial.

The only print driver with source code I've found thus far is a free (but
not public domain) driver for HP Deskjet printers.  I will probably attempt
to modify that driver if I can't find anything else.

Bottom line: does anyone have information about source code to print drivers
or pointers to documentation on how to write print drivers?  Thanks.
