I am ecstatic! For eight months I postponed installing 2004, due to the plotter problems I had updating to 2000. I finally decided to install 2004, then buy a new plotter. When I opened the Plotter Manager om 2004, I find that 2004 has included Cal-Comp plotters in the driver/setup list--2000 did not. They even include soe pen plotters! I installed the 5436 TechJet 720.pc3 plotter, and it works like a charm. Does anyone know why AutoDesk did this (reach back 8-10 years for hardware inclusinos, having skipped them at at least one intermediate upgrade?) Too many like me out here with archaic equipment? Anyway--if anyone else is having problems with older plotters and 2000, 2004 is an answer. Don't know about 2005.
