This is a tutorial for setting up CIS printers on a Linux based machine.
Ubuntu 12 Setup
Open "System Settings".
Go to "Printing".
Click the "Add" button.
The New Printer window will now appear. In that window, expand the "Network Printer" menu and select "LPD/LPR Host or Printing".
Then configure the Host and Queue appropriately. The Host should be set as "printer.cis.rit.edu" and the Queue will be set to the printer which you want to use enable from that computer ("guppy" or "sailfish").
Now click "Forward".
When prompted for a Driver, select "Xerox" and then click "Forward".
You can then select the appropriate driver for your printer (when multiple options are available, select the one labeled Recommended).
Now name the printer and click "Apply".
Your printer is now installed.
