One advantage of the Compugraphic fonts is that (according to an old
InfoWorld) the HP LaserJet III will incorporate Compugraphic Intellifonts
in HPCL Level 5 (or whatever they're up to now). Having a font format
compatible with an INEXPENSIVE laser printer is a really nice advantage.
Of course, Postscript and Adobe fonts are nice, too. 🙂
