AMigaTeX has fonts customized to the printer, so it provides the best
possible print output quality that the hardware can support. My laser
printer is a QMS Kiss with only about 75K of font download memory
available, but I've never run out of space on any documents.
I don't know specifically about the DeskJet, but if a custom printer driver
for it is not already available, Radical Eye Software (the makers of
AmigaTeX) will do one for it.
