I'd still like to see the output of the above command just to be sure.

Most USB DeviceURIs that I find on the web have "?serial=..." appended
after the <model> string. Maybe the problem is that in your case no
serial number is found by the USB backend of CUPS. (I am speculating
here; I never used CUPS with a USB printer.)

You could try:

DeviceURI usb:/dev/...

or

DeviceURI USB #1

instead. (Replace "..." with the exact path to the device node. Run
"invoke-rc.d cupsys restart" or "/etc/init.d/cupsys restart" after
editing printers.conf.)
