The driver talks directly to the printer and not through the CUPS USB 
backend. So the CUPS backed should not be started to not block the port. 
Therefore you must point your CUPS queue to /dev/null. To do so do (as 
root):

cancel -a <queue name>
killall -9 usb
lpadmin -p <queue name> -E -v file:/dev/null

Now you should be able to print.
