unable to locate printer on network change

[Neal Becker]

I have a brother printer at home connected via dnssd.  If I take my laptop
to work and then come home, then try to print it sits in the queue.  Hover
over the printer icon (kde) I see "unable to locate printer".

Rebooting gets the printer working.  Restarting cups does not.
Any ideas?

Thanks,
Neal
