I don't understand how a URI of:

  parallel:/dev/lp0

is going to work for a usb printer. That's what is produced. But then 
there are no other options except parallel port or network printer. I'm 
surely not the only person out here with a usb printer!

Does anyone know how I can go about construction the URI for the usb port?

Presumably, it's something like:

  usb:/...
