I could get rid of the auto browsing/adding with the following: firstly stop cups:
sudo service cups stop then sudo gedit /etc/cups/cups.conf (or using any other editor) and comment... ## browselocalprotocols dnssd save and close then sudo gedit /etc/cups/cups-browsed.conf and set GreateIPPPrintersQueues to No or LocalOnly as described above save and close then stop avahi sudo service avahi-daemon stop then sudo gedit /etc/avahi/avahi-daemon.conf and insert or uncomment the following line: enable-dbus=no save and close now restart the services sudo service cups start sudo service avahi-daemon start You may have to go on and delete all undesirable printers, one by one, three clicks for each (why they make this so hard? In the campus there are hundreds of printers!). You should not see the printers being re- added as before. Final test: restart your system and see the list of printers in Settings.
