Canon IP4200 not printing anymore after upgrade to 8.04

[Marius Groenewald]

My Canon IP4200 was printing fine in Kubuntu 7.10. After I upgraded to 8.04, my printing suddenly does not print. The printer driver is still installed and it shows in my Printers window in System Settings. When I do a Test Print, it says that the info was sent to the printer, but the printer do not print. The Job Queue also shows the file to be printed, but it just stays there.

It is rather frustrating when doing an upgrade and something that was working before, suddenly do not work anymore. I specifically bought the Canon printer, because it had Linux drivers available. Sadly though, it seems like Canon is not helping their Linux customers. Their driver still dates back to 2006. Even the CD Printing feature is not available in Linux.

Thanks for your report.
Please provide the information described here: https://wiki.ubuntu.com/DebuggingPrintingProblems, especially the output of the printingbug info script and your cups error_log.

I don't see a Server Settings in my "System" -> "Administration" -> "Printing" dialog window. The error_log file is empty. I've changed the "LogLevel warning" line to "LogLevel debug" and restarted CUPS.

Is this after trying to print something?

Since you are using a 3rd party driver, does it work after deactivating the AppArmor protection with this command on a terminal:
$ sudo aa-complain cupsd
You can reactivate the AppArmor protection again with this command:
$ sudo aa-enforce cupsd

This is after I tried to print something. Even if I deactivate the AppArmor protection, my printer still does not want to print.

Can you provide a cups error_log with more information?

Unfortunately my Canon printer's powerpack was damaged due to lightning. I used the opportunity to buy myself an Epson printer, which was detected and workable immediately after I plugged it in. Canon will never see me again ... hello Epson!

Closing this bug report then.
