Comment 3 for bug 318886

Also, it is not entirely accurate that the "next print job will clear any canceled print job and print correctly". Although the next print job does go through, I have seen part of the canceled print job (it seems the part of the print job that was sent to the printer before being canceled) gets printed before it so I end up wasting one page of paper. This is a bug.

That is why it's best to unplug and then replug the printer before printing the next print job, not just to stop the flashing but to clear the canceled print job.
