Some more details on the observe issues: - I'm using the Canon drivers from ppa:michael-gruz/canon-trunk. They add a new network protocol shown "cnijnet:/" which doesn’t seem to work with the new kernel - If the Canon printer was installed with previous kernel, it doesn't print because the cnijnet protocol stopped working. You can find the used protocol in the printer settings "device address" - If you try to install a Canon printer with this kernel, it will detect the printer only with the protocol dns-sd and not cnijnet. The printer partly seems to work with this protocol, but not all features are supported (like the Canon printer tools) - The Canon tool cnijnetprn doesn't find any network printer
