printer control from linux

If lp4 isn’t the closest printer to you, then, for example,

export PRINTER=lp7

What’s going on?

lpq -Plp3
lpc status

Get rid of a print job / all jobs / all jobs on all printers

lprm -Plp3 2779
lprm -Plp3 -
cancel -a

Start and stop

cupsenable  lp3
cupsdisable lp3

Of course, how much of this you can do depends on whether the print job is yours, and on whether you are the root user.
