It happens on two plotters - designjet 1050c and designjet 750c. At least some info. gets to the plotter and plots but my ACAD (2002) completely crashes every time. This just starting happening out of the blue. I just got this message on my last attempt: "fatal unhandled c0000094h exception at 6441bo8h", but it usually tells me nothing. When I use the ".pc3" plotters it seems to work fine and no one else on the network is having this problem.
