On a few computers in our office were are experiencing trouble plotting to our HP1050C. Every time we send the drawing to plot, its starts to plot then either shows us a FATAL ERROR screen with the option to save then kicks us out, or, it just kicks us out. I've checked the drawings to see if they are corrupt and they are not. (using recover to open and audit) I've installed the service packs. The printer drivers work because other applications will print to them (ie. MSWord) I'm at a loss. I'm wondering if anyone has any other ideas before I reinstall Acad? We use: Acad 2000 Win 98 HP1050c -Dan
