Cups Printing from the Command Line

Sometimes you just need to print something without going into an application. Here's how...

First, find out what printers are available
lpstat -a

That will tell you what printers are available to you. Then you can print to one of them
lpr -P [printer_name] [file_name]

Need to find out what jobs are running right now?
lpstat -o
(that's the letter oh, not the number zero)

Need to cancel a job?
lprm [job_id]
