"Printer is added" notification spams users.

Issue/Bug Description
With some printers and some network environments, the "Printer is added" notifications can show every few minutes. Even when this isn't the case, it may be annoying for the notification to pop up every time the users logs in, or reconnects to the network.

Steps to reproduce (if you know)
Connect to a network that has an available dnssd network printer connected, eg. an HP.

Expected behaviour
System silently adds the printer, or no action is taken.

Other Notes
Can be disabled with sudo nano /etc/cups/cups-browsed.conf and changing BrowseRemoteProtocols dnssd cups to BrowseRemoteProtocols none as per

Yeah I agree the notifications are excessive and unnecessary; we shouldn't be informing users of the magic happening behind the scenes, printers should just be automatically and silently available when they're on the network.

Another problem; I have added a printer manually (so that scanning works) and when I connect to the network, I have two identical printers added. We shouldn't auto-add printers that are manually added to the system (or, ones that have been manually removed after being automatically added).

Auto adding printers from the network should be option in my opinion. Or at the very least if I delete an auto added printer, it should not re-add itself.
