I've got an identical problem. I've filed a bug report here:
https://bugzilla.redhat.com/show_bug.cgi?id=1700791
I think it was caused by:
https://bugzilla.redhat.com/show_bug.cgi?id=1662408
I don't think it's triggered by "Shared"; but rather by
"AuthInfoRequired" that changes from None or Username,Password to
Negotiate.
To work around it, here's what I did:
- move /usr/lib/cups/backend/smb to /usr/lib/cups/backend/smb.real
- write a script /usr/lib/cups/backend/smb to replace it:
#!/bin/sh
cat - | /usr/lib/cups/backend/smb.real "${@}"
Remember to make it executable. You'll notice this just calls
smb.real. The actual change is that this script exits with 0, so Cups
never sees an error. Suddenly it doesn't trigger AuthInfoRequired, and
actually prints.
NOTE: this will be overwritten every time cups is upgraded. The
workaround can be smarter if you change DeviceURI to something else
(say smbworks://) and create a script accordingly.
I do this at work for a printer that has every non-SMB port firewalled.
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.
