[sane-devel] Running sane din docker

Sat Jul 29 18:32:48 UTC 2017

Ah. I'm running saned in a container, which runs on the host which has
the usb scanner plugged in. I want to share that scanner over the
network to other machines.

The scanner is a HP PSC 1200, supported through hpaio (and works great).

Hpaio backend is version 3.16.11.
Sane is version 1.0.25
