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?

Just a hunch, but did you disable/mask cups-browsed in response to the recent CUPS CVE?

Other than that, how are you discovering the printer when you relocate? IP, DNS name? Can you resolve it, ping it, telnet/nmap to the appropriate ports?
