Interesting discovery. I created Xubuntu 11.10 liveCD, loaded without installing, checked Settings:Printing, and there was my usb Brother MFC-8840D printer automatically detected and setup! Device URI: usb://Brother/MFC-8840D?serial=000M4j407389. What is difference between Xubuntu and Ubuntu that allowed Xubuntu to detect usb printer?
