Q: How can I stop a runaway job on my personal HP printer (e.g. LaserJet 6 or 2100 series)?
First, make sure the job has been removed from the queue on the computer you were printing from (see FAQ #8).
Then, power off the printer.
If it is still spitting out paper after you turn it back on, repeatedly press the ``cancel job'' button (usually the one with a triangle on it) until it stops.
