Same here, HP Laserjet 4000 duplex. It has something to do with the parallel
port, but can be ignored, I think.

There has been a workaround suggested, but I'm not sure I'm providing the
correct setting which has to be placed in /boot/loader.conf:


I didn't have this message when using parallel printer on FreeBSD 5.

As you stated, the message repeats many times, but doesn't seem to have
any effect on printing.
