Recently while trying to fix a printer I used lpr a bunch of times. It’s not exactly new to me, but never fails to surprise people when I use it.

lpr submits files for printing to your default printer in OSX.

Print a file:

lpr README.md

Print two copies to a specific printer:

lpr -# 2 -P specific_printer README.md

This is an invaluable command-line trick.
