I think you discount a kernel problem too lightly. When CUPS has started a print job it has to send it to the printer. In my case over the network. This involves the kernel and or the network driver.
I have just tried the daily build of Ubuntu Gnome - the browser can not find google and ubuntu Budgie - same problem. The ppd file for the printer is present in both distributions. I will re-install Ubuntu tomorrow and try again. 17.04 works perfectly.
