I did some more testing. The 32-bit trusty live cd can print, the 64-bit live cd cannot. In both cases I installed the canon 2.80 drivers (Linux_UFRII_PrinterDriver_V280_us_EN.tar.gz), and used the 32 bit and 64 bit deb files respectively from it, after installing the necessary dependencies of course (apt-get install libglade2-0).
The same drivers (v2.80, 64bit) work on my 64-bit Saucy installation. So, something's miss with 64-bit trusty as far as this printer is concerned. I tried both style printer paths: usb://Canon/MF4100%20Series?serial=SDF84010xxxxx&interface=1 and cnusb:/dev/usb/lp1 - Both device paths work on 32 bit trusty 14.04 - The longer usb:// path works on 64 bit saucy 13.10 - Nothing works on 64-bit trusty 14.04 (even though when adding printer, it detects them and chooses the right driver just fine) No error shows up when I try to print, I just see" Idle - Sending data to printer" but the printer stays completely idle and unresponsive.
