Plotting on linux now works fine. Just use the postscript driver for the plotter.
Best C and D-sized plots come from printing to a file and opening and printing the file in Illustrator on a Windows machine–This will be true until a new driver is developed for linux.

Been having problems printing to C and D size paper on the plotter. Our plotter is an HP DesignJet 800PS, with ip address 10.135.152.15. The ppd file that comes from HP or from linux doesn’t work quite correctly with this printer. My solution was to take the ppd file from my Mac, edit it to take out all of the Mac-specific lines and use that.

The file is saved in /net/sw/edg/printerfiles/dj800.ppd. I then added the plotter with:

lpadmin -p plotter -P /net/sw/edg/printerfiles/dj800.ppd -v socket://10.135.152.15:9100
accept plotter
enable plotter

This does NOT work perfectly. It stil seems to cut off the very end of documents. But, that could be acceptable for most things. And that’s probably as good as it’s going to get. If a perfect printout is needed, the solution is to print to file and the plot the file from a Windows machine, where they have drivers that work.

Print command: lpr -Pplotter -oPageSize=AnsiC file_to_print
