Each desktop users on Ubuntu (16.04, 18.04) are looking in that print server to retrieve those printers. It works fine but... # /etc/cups/cups-browsed.conf in a desktop user ... BrowseRemoteProtocols cups dnssd BrowsePoll 192.168.10.80:631 # CUPS server ... Each time that an CUPS update is applied on the client side all printers disappear from the listing and users are unable to print. So i have to connect to xxx computers in our company to restart the cups- browsed service... This problem exist from some years.. but still not resolved and i didn't found a way to fix it. Workaround: - sudo service cups-browsed restart OR reboot the computer Thanks!
