When CUPS won't die...
I upgraded CUPS yesterday and apparently broke my printing. After some googling and searching on the Gentoo forums, I came up with the following: 1) Delete the printer from http://localhost:631/printers/ 2) killall cupsd (perhaps using the PID and -9 switch if the bastard won’t die) 3) /etc/init.d/cupsd zap 4) /etc/init.d/cupsd start 5) Add the printer back into the web panel
It works now.
(Note that you could probably fix the problem with a reboot, but that’s just so Windows-like.)
