Well, thankfully the solution was much easier than all of that. :-) I
had ben using my printer for nearly 6 months, so I was highly dubious
that the problem was at the kernel level.The deal was I had some kind of
zombied print process that showed up under a "ps aux | grep root".  The
entry was something like "parallel: /dev/lp0 <filename>".

All I had to do was kill -9 that job and the rest of the print queue 
was fine.
