Summary: looking for driver or hints

Yesterday I decided to hack up a driver that will allow me to
do a graphics screendump using the GEM menu command 'print screen'
or the <ALT> HELP keycommand on my C-Itoh 8600M printer.

I realise that this effort is probably double work, I'm sure
somebody must allready have done this for other non Epson
printers.

Questions :

  1 - If you have a binary driver for C-Itoh 8600 or source to
      another printer driver, please mail it to me.

  2 - Does anybody have the _prtblk documentation. It is missing
      in my (very early) development kit. It looks like that
      code is general enough to handle screendumps to any printer,
      if I only knew its parameter block meaning.

  3 - Does anybody know a (assembly level) call to the equivalent
      of bconout(0) that works from inside my screendump handler
      (that is called from the BIOS through the $502 vector).
      Claims that the BIOS is reentrant seem to be contradicted :
      using the normal trap interface to bconout hangs the system.

Offer :

  if you are interested in such a driver, you are welcome to my
  source and code once I solve the problems. Mail me.
