[comp.sys.amiga] Help for me and my canon

    I have a canon color ink-jet printer (PJ-1080A) which I use with prowrite
I have a major paper due friday, and am wondering if there is any way to fix
an annoying problem. Whenever it prints a line of graphics (including
ProWrite "text") it occasionaly prints some garbage at the end of the line.
A closer inspection of this phenomenon reveals that this only happens when
there is no more "real" information left on the line to print, and the
"garbage" it prints is the same info it printed in those locations on the
previous printing pass. What it looks like is that the print-drive was
was written badly. My guess is that dump_rast() uses a 1 line buffer. When
it has loaded all the information that a line has, it simply quits putting
information in the line, rather than filling the rest of the line with 0's
like it should. This is usualy no problem printing pictures, because they
have information from end-to-end, but makes parts of my ProWrite documents
look kind of goofy. Is there any simple way to fix this? Has someone written
a "correct" PJ-1080A print driver? If not, how could I fix it?

   Also, is there anywhere I can find out what EXACTLY the different printing
options (esp. dithering) do. Experimentation works, but uses up lots of
paper!
