I have some problems with printing to my HP designjet 430 trough my network. We are running AutoCAD LT2004 on Windows 2000 pro and our network is Windows 2000 server. We can't send more than one drawing to the plotter at time. It makes an printing error. Our printer driver is installed directly on the server and PC3 files are locally set up on our 2 workstations. I've tried to send many word documents and it's working properly. Can anybody help me ?
