The pr command is intended to format a file for printing. For example, let's say the file named foo.txt has the following content.

Hello World
How are you today?

The PR command has a number of options to format the file. -n numbers the list, and -h adds a header named "Greetings".

pr -n -h "Greetings" foo.txt > bar.txt

Before printing, you may want to use the lpstat or lpc commands to list the available printers.

There are a few different commands that can be used to sent print jobs to the printer.

• lp (Line print)
• lpr (Line print request)
• lpd (Line print daemon)

The lpq command can be used to view and cancel print jobs in the print queue. The lprm command can be used to remove print jobs.
