Broken Printing

Hmmm. Well printing on cups via IPP from Windows machines broke on Dec. 2 for no apparent reason. My laptops still talk to cups on my linux box, they show up in the logs, and their jobs show up fine as “Completed” in the cups queue. But they never get sent to the printer. And there are no errors. Just silently it all doesn’t work. I can still print locally from my linux machine fine. In the cups access_log and error_log it looks as though all clients are connecting and submitting jobs fine, but in page_log, none of the remote jobs show up as being printed.

Anyone who might know why this is happening? If so leave some comments. Or post a reply to my plea for help. I can’t think of anything I changed before it stopped working. It’s possible I up2date’d something, but I can’t think of anything related to printing.

If anyone has an idea how to start debugging this I’d be happy to know too. I made the logs capture everything with the “debug2” setting, but it still didn’t show anything unusual except the absence of printing.
