The Kyocera printer uses its own native lay-down language, Prescribe, and
a close but not exact imitation of the HP LaserJet escape-coded
language. This driver was supplied by Kees Straatman, of the University
of Groningen, and is now maintained by Sietse Achterop, Computing Science
Department, University of Groningen. (mcvax!guvaxin!sietse).
Kees Straatman found that the emulation of the HP LaserJet was too
inexact to make it worth while to work with that language, and so
concentrated on "Prescribe." for the Kyocera. It might, nevertheless
be possible to take his code and make it work on a Laserjet.
