Common Unix Print System

UMIACS has replaced our LPRng printing system on our UNIX systems in favor of the industry standard CUPS. This provides us with better support for printers and their specific options.

Printing is only available from UMIACS Networks or when attached to the UMIACS VPN.

A list of printers can be found using,

You can see documentation about printing from the command line on our RHEL/Ubuntu hosts at (available only on UMIACS Networks)

Differences between our old LPRng print system

  1. To duplex you need to specify -o sides=two-sided-long-edge instead of -Zduplex the same way. -o sides=two-sided-short-edge can be used for the other duplex orientation. You can create a personal instance of a print queue that has your defaults, more information is available here.
  2. Using the lpr command is available, although the lp command is the main supported command and has more functionality.
  3. Since now the CUPS and WindowsPrint systems are now discrete there can be jobs in the queue from the other print system that if misbehave cause the other print system queue to stall. Please contact staff for assistance if you run into a problem.
  4. The queues are all no banner queues by default. If you would like to change this behavior for your account you can run lpoptions -o job-sheets=standard QUEUENAME
