My company has (6) users (4 proe and 2 solidworks)sharing an old HP designjet 600. It takes 20 to 30 minuets to get one line drawing out of it. Forget about any type of rendering or color plot. We have tried upgrading the memory with no real improvment. My question is, is there anything I can do to get better performance out of this plotter or do I need a new plotter? If I were to get a new one what would it be? We average about 10D size prints a day. I don't want to break the bank for such a small number of drawings. Any sugestions?
