I am trying to add Airplay-compatible zeroconf advertising for a HP Laserjet 2300 which is connected directly to the network. In particular I am not using CUPS. I am able to see the service with avahi-browse -a but iOS does not seem to find it. What am I doing wrong? The following is my services file. I also have an entry in /etc/avahi/hosts with 192.168.2.11 hp-laserjet-2300.local <service-group> <name replace-wildcards="yes">HP LaserJet 2300</name> <service protocol="ipv4"> <host-name>hp-laserjet-2300.local</host-name> <type>_printer._tcp</type> <port>515</port> <txt-record>product=(HP 2300 Laser Printer) pdl=application/postscript,application/vnd.hp-PCLXL Color=F Collate=T Staple=F</txt-record> </service> <service protocol="ipv4"> <host-name>hp-laserjet-2300.local</host-name> <type>_ipp._tcp</type> <port>631</port> <txt-record>priority=20 product=(HP 2300 Laser Printer) pdl=application/postscript,application/vnd.hp-PC LXL Color=F Collate=T Staple=F</txt-record> </service> <service protocol="ipv4"> <host-name>hp-laserjet-2300.local</host-name> <type>_pdl-datastream._tcp</type> <port>9100</port> <txt-record>product=(HP 2300 Laser Printer) pdl=application/postscript,application/vnd.hp-PCLXL Color=F Collate=T Staple=F</txt-record> </service> </service-group>
