I think someone else mentioned that HP HPGL/GPGL drivers are still within Windows. Make sure it is actually a serial or parallel interface. Many HP plotters use a DB-25 which looks like it might be a serial connection, but it is a different interface who's name escapes me at the moment.

Good question. When I did some tests with an Epson 5000 and 3000, I was using some 1/32 inch PCB. I've since then gotten a couple of R200 which I know will take 1/16th inch in the CD tray without modification. And an Epson 4800 that needs some work that I am pretty sure will take 1/16th, too.
