>When my printer job does not succeed (PostScript error, paper out, pushing the Job Cancel button on the printer, ...) then "lpq" on my machine says "Printer is stopped", and indeed no progress will be made on any print job for that printer. So how do I restart the printer?
Whatever the rationale is, the default for this on CUPS could hardly be more unfriendly. This sort of thing makes it look like a full employment program for system administrators. No wonder people want to replace it.
