Try a serial URI

ex: serial:/dev/ttyUSB0?baud=11500

Also note: I think (without being absolutely certain) that you only use
1 / when you refer to a file (or a device note) directly on your system,
use // when your are specifying a network resource.  I don't know if
that matters or if CUPS is smart enough to figure that out on it's own.
 ( // also seems to be used by USB printers that are named by their
model number rather than a device note, for examply, in my system, I
have usb://Samsung/ML-1740  compared to parallel:/dev/lp0)
