Hi @Noitidart,
My system is: Ubuntu 16.04 LTS
When the option is turned on, this is what I get-it's a window-:

And then, nothing happens.
Executing: ps -ef | grep lp
Gives: lp 4946 4939 0 04:00 ? 00:00:00 /usr/lib/cups/notifier/dbus dbus://
And that process stays "alive" a very long time.
Now, when the option is turned off, the printer configuration window shows up, and everything is going fine.
Regards,
@tojazmin
