Apple AirPrint service problems

[Cisco Tech]

I am not having any success getting AirPrint to work with my wireless iPad clients. I have a CISCO WLC 8510 running 7.4 code and all CISCO APs.

I have configured the mDNS settings per this document:

I verified that I can see the printers and the AirPrint services per this document:

AirPlay is working for the network. I have 5-6 AppleTVs that are functional for both iPads and MacBooks. The printer services will not show up anywhere! Any suggestions or more configuration changes for me to try?
