#HP DeskJet 500 C driver
It appears that you can patch the HP_PaintJet driver which to output to the
HP_DeskJet_500C. The driver sorta works as is but since it thinks it's a
180 dpi printer, it only prints on the left 2/3 of the paper. Patching the
driver to indicate that it is a 300 dpi printer seems to do the trick. I'm
testing out the mod further and will post the results later.
