>Description:
	I've tried printing a pdf file. I have apsfilter installed. The printer
(HP Deskjet) made a couple of weird sounds and started blinking the out of 
paper light. I turned it off and on. Light blinking again. lprm the job -- 
still blinking. Turn off and on a couple of times -- and computer is hanging. 
Reproduced twice now. Printing worked fine before upgrade to 4.5 (from 4.4)
I've had similar problem before I beleive. It was caused by some sort of
apsfilter misconfiguration. So looks like there is some problem lurking around
in the parallel port driver code...
>How-To-Repeat:
	I don't think it's easy to reproduce that. Required some kind of weird
apsfilter problem which makes printer go crazy and do something bad to the os.
>Fix:
