Yes, the same log entries appeared each time I re-enabled the printer.
It tried for 20 seconds and then gave up and disabled the printer again.

I'm guessing that the problem will probably go away after a reboot, but
I don't like telling users that they need to reboot Debian to fix
things.  I did try rebooting the printer though and that didn't help.

I'm not familiar with HPLIP or avahi, would you know anybody who could
comment on this or suggest further details I should obtain from the
system before it is rebooted?
