UMIACS uses the industry standard CUPS (Common Unix Print System) for printing on Linux systems, providing better support for printers and their specific alternatives than other options.
Printing is only available from UMIACS Networks.
A list of printers can be found using,
- http://print.umiacs.umd.edu/printers (available only on UMIACS Networks)
- lpstat -p
You can see documentation about printing from the command line on our RHEL/Ubuntu hosts at
Changes from the old LPRng print system
Duplexing
To duplex you need to specify -o sides=two-sided-long-edge instead of -Zduplex when submitting your job. -o sides=two-sided-short-edge can be used for the other duplex orientation. You can specify defaults or create a personal instance of a print queue please see this documentation.
Commands
Using the lpr command is available, although the lp command is the main supported command and has more functionality. We encourage you to use the lp (SysV) commands.
Discrete Queues
The CUPS and WindowsPrinting printer queueing systems that UMIACS runs are discrete. This means that problematic jobs from one queueing system that can cause the other queueing system to stall. Please contact staff for assistance if you run into a problem.
