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.
