His name is Pavel Houda. The problem with a PostScript -> HPGL filter is that PS is a much 'richer' language. It is certainly a non-trivial exercise if not impossible. PostScript is a full page description language and HPGL is a plotter driver language. What would one do with legitimate PostScript code which could not be done in HPGL? For example, what would one do with the PostScript code to define a color image bit-mapped font, which also contained some characters which are drawn and filled rather than bit-maps and then prints these characters at several rotations and scaled sizes? It may not be impossible; however, it is most likely not worth the effort. The code would probably cost you more than the PostScript printer. An HPGL driver for your software would likely be an easier solution than a PostScript -> HPGL filter. If you see Pavel, please tell him I said hello. -- Robert Grove Arnav Systems, Portland, OR tektronix.tek.com!reed!arnav!rgrove
