The CUPS Browsing and BrowsePoll configuration directives are no longer handled by CUPS itself. Instead, CUPS uses DNS-SD to advertise print queues on the network. Discovery is performed by the applications. GTK+ applications do this as part of the print dialog implementation. To use DNS-SD, enable the "avahi" service and make sure to allow mDNS (UDP port 5353) through the firewall.

If this solution is not suitable for your site you can continue to use CUPS Browsing as before by using the cups-browsed service. The browsing configuration has been migrated to [link:cleanconf/etc/cups/cups-browsed.conf] and the cups-browsed service will be enabled after upgrade.
