I've figured it all out. Seems the printer allows a <Esc>Q to go into
graphics mode and a <Esc>[t to go out of graphics mode. Everything in between
it accepts as raw data from bits 0 to 5. Bits 6 and 7 are ignored but should
both be set to allow the printer to accept 0 for no bits on. I am going to
upload a text file which has a sample C program to dump a single bitplane
image to the 920 printer. I do not know how it could be added to a driver to
do the dump though. I've written this at work so I can dump images from the
screen to the Printek 920 and it works pretty well but it is extremely slow.
The example in the manual is corrent, but it prints the box so small that it
just looks like a solid block of dots. Try sending <Esc>Q to the printer
then about 80 question marks then a <Esc>[t to the printer. You get a solid
line. (send this to PAR: not PRT: ) Create a file with the hex bytes $1B $51
$3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $3F $1B $5B $74 $0D
$0A
IN IT THEN DO THE FOLLOWING FROM CLI [TYPE <filename> to PAR: This should
print a solid line across the page. It may only be an inch or so long. IF
you can do some programming then get the file I am sending up and dump the
stuff to PAR: Rob
