HP LaserJet P1109w fails to print on Ubuntu 16.04: Invalid usb_open: Permission denied

[Max Timchenko]

A full write-up of this bug has been posted at https://gist.github.com/maxvt/7b1e32cd28e37a8f8de6cfacae76ae8a

The USB device created for the printer is assigned saned group, not lp group, apparently due to interaction between udev rules for saned and hpmud.

I do not have scripts output from when the problem was present. This is with the problem fixed as described in the gist.

The interaction is between the rules for hpmud and those provided by the scanbd package.
