Printer keeps printing spewing pages

I print using cupsys.
Sometimes an error develops in the printing chain. The printer
begins spewing forth sheets with a single line of ascii on it.
I can delete the job, via the kde control panel or the cups web interface,
However this does not stop the problem. I detach the printer plug. i replug in
and the printer continues to malfease.

What to do?

ps aux|grep lp
kill -9 {all processes owned by lp}
and turn off printer.
then it will stop and you can go back to printing.

Yay!
