Same errors are written to the syslog on my desktop. I too do not
have anything attached to a parallel port.
Could this be some kind of emulation? Like the SCSI emulation used
for CD drives in the past? I have an HP USB printer which uses
usblp0:
root@valinor:/root# grep lp /var/log/kern.log
Nov 12 11:02:31 localhost kernel: drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 23 if 0 alt 0 proto 2 vid 0x03F0 pid 0x8204
Nov 12 11:03:00 localhost kernel: drivers/usb/class/usblp.c: usblp0: removed
I tried to stop cupsys and/or lpd and the messages stopped when lpd
was stopped. And after starting lpd again they began appearing
again. So lpd appears to be the culprit. I could print fine when lpd
was down (I use Cups) so I'm going to try and remove lpr from my
system. Perhaps you can test this as well?

Bram
