Comment 8 for bug 1863375

The usb://... URI uses the CUPS backend. A hp:/... URI is
used by HPLIP with its own hp backend. Using this backend
gives a user the ability to scan *automatically* without
any further setting up. The hp:/... URI should have been
shown by lpinfo. Here is what should have been seen:

 hp:/usb/hp_laserjet_100_colormfp_m175nw?serial=00CNC9CBV02R

Plug this into lpadmin and test printing and scanning.
