Printing question

[R Kimber]

If a job has been sent to the printer, but is then removed from
the printer queue before it has been completed (because it is not
printing correctly) and the printer switched off, what happens to the
job?

I would expect it to have been deleted, but on switching on my printer
again, it continues to spew out unwanted pages, some with a line of
what looks like postscript on them, so it must be spooling a file to
the printer.

How do I stop this behaviour?  I.e. how do I abort the job when the the
print system shows no jobs being printed?

Ubuntu 5.10, 2.6.12-9-amd64-k8-smp
