The School of Computing uses a Common Unix Printing System (CUPS) server to manage printing, using the Internet Printing Protocol (IPP). CUPS provides both lpr and lp style client commands under Unix.  Printers are only accessible from within the department's network.  If you wish to use the SoC printers from outside the school's firewall, you will need to use the VPN system to establish a link into the school network first.  (NOTE: The UConnect wireless network is outside of our firewall.)

The main public printer is csps for single sided printing, and csduplex for double sided. The printer is located in MEB 3401.

Various research groups, labs and grad student areas have printers available for their use. You can get a list of printers (under the "Queue Name" column) and other information using the printer web page or the lpstat command:

lpstat -t

Ignore the bogus date fields. The lpstat man page explains more options. Various printer options, defaults and such can be set using the lpoptions command. For example, to make grduplex your default printer, you would run the command:

lpoptions -d grduplex

With a default destination printer set, you can just do "lpr filename" instead of "lpr -Pgrduplex filename"

Documentation for the CUPS system is available via the web.

Windows

On systems running Windows, the printers are available through cups using the form

http://printspool.cs.utah.edu/printers/name_of_printer_here

You may need someone with admin privileges to add the printer and share it before regular users can make use of it.

Macintosh

On Macintosh systems, open the Print & Fax preference pane.  In the dialog set the protocol to "IPP" and in the Address (Printer on older Macs) field enter:

printspool.cs.utah.edu

In the Queue (Spool on older Macs) field enter:

printers/name_of_printer_here

In the Name field, you can name this printer entry to anything you'd like.

Configuring a Self Administrated UNIX System Using CUPS

There are two quick methods to allow a UNIX system within the SoC network to access the CUPS server.  If you wish to make the change globally for all users of the system, edit the/etc/cups/client.conf file and add the line:

ServerName printspool.cs.utah.edu

If you only wish to make the change for your user account on a UNIX system, simply set the $CUPS_SERVER environment variable to "printspool.cs.utah.edu".

If you have troubles with printing, first make sure it isn't something obvious like the printer out of paper, jammed, offline or the network cable unplugged. If there is a non-obvious problem, send a message describing the trouble in detail to .
