I am in the process of upgrading my CAD stations from Windows 2000 Pro to XP Pro SP2. I'm doing a clean install of XP (format drive, re-install OS). Once I've installed AutoCAD 2000i and Service Pack 2 I go to the Plotter Manager to set up my PC3 files. I've noticed the following: 1) I can't add a new plotter configuration if it uses a system printer. 2) If I go into AutoCAD itself, enter Plot, then select the system printer, AutoCAD will generate a PC3 file for the system printer, but once created, I can not use the Plotter Configuration utility to modify it. Is this a known issue? If so, is there a way to resolve the problem?
