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.

I just had this issue of being spammed by "Printer added" notifications every few minutes, for a Brother HL-1210WE printer I have on my network, after I installed the drivers for it.

It was really annoying, and the only temporary solution I found was to disable cups-browsed.

I agree with @cassidyjames 's comment, we should just have network printers available when needed, and if there is a real need to keep "adding" the printer under the hood every 3 minutes, we shouldn't be notified of it.

I've been having this issue on Pop!_OS 20.04, with Gnome 3.36.1, cups 2.3.1-9ubuntu1.1. Printer is a Samsung M2830dw. Issue started after upgrading Pop!_OS.

A bugfix has been filed upstream in Ubuntu's fork of gnome-settings-daemon.
