I don't think that's the explanation here. In the past (e.g. with OS/2)
just switching off has always prevented further attempts at printing so
long as the job has been killed. I think the issue lies with the
processes that were still running after the job was removed from the
queue. Killing these processes solved the problem.

The issue, I suppose, is: is why didn't removing the job kill the
processes?  Is it a bug in the printer control package?
