Can’t say why it’s not working for you. Seems like it’s only working part time for me as well, but I’ve been too tied up doing real work to look into exactly why. So it probably won’t get fixed until I really really need to print something and can’t.

As for troubleshooting, I’d say take it step by step.
0) reboot your router (sometimes it helps).
1) reboot your linux box.
2) verify you can print a test from CUPS.
3) verify that another linux box can print to the printer by it’s air-print share name.
Once these are done, then throw apple into the mix.

jrogers@pumba:/etc/avahi/services$ avahi-browse -a | grep AirPrint
+ eth0 IPv6 AirPrint HP1100 @ pumba Internet Printer local
+ eth0 IPv4 AirPrint HP1100 @ pumba Internet Printer local

Still not seeing it on the iphone though. No clue why.

Syslog shows avahi not complaining about the .service file (loads ok), but I noticed that the file generated by tjfontaine’s script dMid not generate the adminurl line. I tried manually adding it, but that didn’t help either. My iphone still doesn’t see the printer. The macbook doesn’t either, but that may be because its already installed (don’t want to remove it to find out)

Any pointers on how to troubleshoot further? How can I see what is avahi browsable ?

Sorry for the late reply. I was not able to apply this on the ReadyNAS NV+ because it got stroke by a lightning(!) and was burned down via ethernet cable (the ethernet cable was not plugged into the UPS unit).

Thanks for the excellent guide, I’ll try to apply it on my ReadyNAS NV+ server when I get back home
