You will sometimes have better luck if you 'lpc abort' the queue,
wait a few seconds, and then 'lpc start' it.  Of course, that
doesn't solve the actual problem...

I have not heard of it.  I'd like to see some actual proof of
what is happening (like a tcpdump) before assuming that it's
lpd's fault.  Mind you, I'm quite willing to believe it's lpd's
fault, but I can't very well look into the problem unless I know
what sequence of packets is causing it.
