One of the printers connected is a Calcomp 5835 Electrostatic Plotter. Because of the size of the files we're printing, we're using the lpr -s option to send the files to the plotter. When we send a large file to the plotter, it bogs the system down to the point where the keyboard stops responding, and everything else basically hangs for a (too long) while. I can understand maybe slowing the system down a little, but completely dead for long periods of time (> 10 minutes) seems a little much. If anyone has any suggestions, recomendations, pointers, we will be most grateful. We've tried some experimentation with xon/xoff but haven't figured it out .
