CUPS uses Avahi internally when built with the zeroconf USE flag to scan for printers on the local network. To use Avahi hostnames to connect to networked printers, set up .local hostname resolution and restart the CUPS service. CUPS and cups-filters need to be built with the zeroconf USE flag as well. Use the driverless command for listing available printers.
