Comment 6 for bug 1868475

The error was "Unable to connec" as I've already posted.
It was derived from lack of mdsn resolv capabilities for lpadmin.
system-resolvconf and network-manager need to have both mdns enabled https://gitlab.freedesktop.org/NetworkManager/NetworkManager/issues/136.

I've enabled from both and driveless is working from GUI.

I had the impression that with the driverless printer I had less printing options to control on the gui than hplip with 3830 workaround. Is it plausible?
