How can I quickly and cleanly kill a print job?

On occasion, I've tried to kill a print job started in error, to avoid a waste of paper and toner. I know there are several layers to the printing system in use, and the GUI printer queue applet is not particularly responsive. What's the quickest way to kill and purge a print job?

Solution 1:

From the command line?

lpstat -o|more

will show a list of pid numbers and then...

cancel {pid number}

You might need to turn the printer of to have the printer cancel what is already in its memory.

Solution 2:

Try opening cups in a browser window (localhost:631) and cancelling from there.
