You can test the mdns service by enumerating the local network:
Some familiar devices should appear in the list.
Common Unix Printing System
Enable the daemon
rcctl enable cupsd rcctl start cupsd
Browse to http://localhost:631/admin and add a new printer. The network printer should appear under 'add printer'

Install the package. No further configuration is needed.
Apps such as web browsers and PDF readers should be able to print.
