We just got a QMS PS-1500 PostScript printer which has a
Ricoh 4150 engine. At first we used the pk300 Canon-based fonts.
Installing the write-white pk fonts (which I believe use the
RicohFortyEighty mode_def below) improved the print quality
considerably.
But can we do better? The thinner strokes break up slightly and give a
general feeling of hesitancy (say). Has anyone tinkered with the
4080 mode_def and come up with anything worth calling a 4150 mode_def?
Would anyone care to share their experiences with blacker, fillin and
o_correction? The last two I note are in double danger bends so I
thought I'd ask for advice.
Thanks,
Gary
