If I do the smb.real trick, I'm able to change the "Shared" and the
"AuthInfoRequied"
but even now I cannot print. In the "gnome-control=center" the jobs end up
"paused". I get a pop-up-bubbel in my gnome session telling me that
"credentials are required". I thought they should be picked up from the
DeviceURL.
