You can also try using the web-based cups interface, go to
http://localhost:631 and you can get documents, and configure printers etc. You will probably need root access.
I would recommend you contact SCS for support, you might even find the right file to download onto your laptop somewhere on the website, although a quick look around seems to only show for lprng... Maybe someone in your group was running CUPS, but it doesn't seem to be site-supported.
