Programming a printer driver (ARRG)

[Brent Bates ViGYAN AAD/TAB]

   What I have done in the past is to use an image format that is produced
by a lot of our "standard" software as my image standard format.  I have
good documentation for this "standard" so I know all the in & outs of it,
which is unlike the iris.rgb files.  When we got our Tektronics 4693D
thermal hard copy unit, I got a device driver manual from Tektronics that
fully documented the printer commands and wrote a conversion utility that
converts my "standard" image files to 4693D files.  I then use lpr with
the parallel port to send files to the printer.  If you have good
documentation for everything, you can do almost anything.
