Can you please run the following commands and post their output here:
sudo /usr/lib/cups/backend/usb sudo modprobe usblp ls -l /dev/usb/lp* sudo usb_printerid /dev/usb/lp0 sudo usb_printerid /dev/usb/lp1 sudo rmmod usblp
Can you also try the CUPS packages (cups + cups-filters, a backport from Precise) from my PPA:
https://launchpad.net/~till-kamppeter/+archive/ppa
Does this alternative CUPS version detect your printer?
