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.
