You see, one could modify pprdrv so that when it is killed, before dying, it sends a command to the printer to clear the display. But this wouldn't work if the printer weren't accepting data. So if you take a printer off-line during a job and then cancel the job, nothing will happen until you put the printer back on-line. If a job got "hung" for some reason, it would be un-cancelable! Now there are probably effective ways to deal with this, but the code isn't simple and I haven't written it yet.
