 Printing on the department-run Unix and Linux systems is [[:computing:department:unix:printing|covered elsewhere]]. These instructions refer to self-managed systems.
+===== Wired network linux printing =====
 The simplest way to use the Physics print queues is to use CUPS print software on your Unix/Linux system. This is the default print system for most current Linux distributions.
-===== GNOME Setup =====
-To set up CUPS in GNOME, go to **System -> Administration -> Printing**
-{{:computing:network:print:screenshot-printer_configuration_-_localhost.png|}}
-In the menu go to **Server -> Settings...**.
-{{:computing:network:print:screenshot-basic_server_settings.png|}}
-Under basic settings check **Show printers shared by other systems**. Close out of basic settings (click **OK**) and then reopen it and click **Advanced...**.
-{{:computing:network:print:screenshot-advanced_server_settings.png|}}
-Under Browse Servers click Add and type **cups.spa.umn.edu**. Hit enter and click OK and then OK again to close the basic settings. The Printer configuration window should now begin displaying all of the physics print queues.
-===== Command Line Setup ====
 Find your ''cupsd.conf'' configuration file (usually it's ''/etc/cups/cupsd.conf'') and add a line:

 After restarting the cups service on your computer (eg ''/etc/init.d/cups restart''), all the network print queues should be available to you automatically.
-If using CUPS, check for print queues using the command line tools such as "lpc" and "lpq". Send print jobs using the "lpr" command. The graphical printer configuration tools provided with most linux systems are unlikely to work correctly.
+<note warning>
+In Ubuntu 13.10+, you need to add the BrowsePoll line to ''/etc/cups/cups-browsed.conf'' instead of ''/etc/cups/cupsd.conf'' and restart the ''cups-browsed'' service instead of ''cupsd''.
+</note>
+===== Wireless network laptop printing (laptops etc) =====
+You can either:
+  - use the method above for wired printing
+  - set up a local print queue on CUPS using port 9100 (jetdirect) directly to your chosen printer hostname.
-For systems which lack CUPS, you can send print jobs using the lpr/lpd protocol through our print server, ''lpr.spa.umn.edu'', which will accept print jobs from any system registered in the Physics network. Please refer to the man pages on your system for exact details on how to set up printing.
+The second method is probably preferable for a laptop, as it will eliminate your cups system from trying to poll ours even when you are not elsewhere, but the first gives easier access to all the available print queues.
-Do not depend on sending data directly to printers (hostnames or IP addresses), as they may be changed or access control may be enforced. The only supported way of printing is through the CUPS or lpd queues documented here!
