After sending a plot to our HP750c plotter, the plot is almost finished but then just stops. The only way to get it working again is by booting it and re-sending all the plots all over again. I have searched the discussion group and can not find this problem out there. We have replaced the NIC/server, and also the que. We are now waiting on the HP Tech to come out and try again. I wondered if a plotter, with an IP address, could possibly get a virus? Thanks!
