You can use the flpr command to print a file:
flpr [option] filename
This is a Fermilab-specific command which supports printing.
flpr has many options and both system and user defaults.
More details are available with
man flpr.
The first example below sends a file to your default printer. The second example sends a file to a specific printer served from the default print server (fnprt.fnal.gov). The third example sends the file to a print queue on a specific computer:
flpr myfile.ps
flpr -q b0trwqms_ps myfile.ps
flpr -q b0trwqms_ps -h fnald.fnal.gov myfile.ps
