Implementing AirPrint with DNS-SD

# Background # I'm trying to implement AirPrint through static DNS, like documented on http://dns-sd.org/ServerStaticSetup.html . The iPad gets the dns search domain "lan" through DHCP, and I verified that in Settings-WLAN. I think I created all necessary entries in the right places, the iPad however doesn't find my printer or if it happened to find it, it showed a lock after the printers name and didn't print. (iOS version is 6.0.1) Has anyone here a clue, as to why iOS does not find the printer or if it finds it, why it shows it as locked? This is my setup (simplified with example domain) ## DNS entries ## ### Redirect to browse domain ### PTR b._dns-sd._udp.lan = bonjour.lan PTR lb._dns-sd._udp.lan = bonjour.lan ### Printer entries ### PTR _ipp._tcp.bonjour.lan = TestPrinter._ipp._tcp.bonjour.lan PTR _universal._sub._ipp._tcp.bonjour.lan = TestPrinter._ipp._tcp.bonjour.lan SRV TestPrinter._ipp._tcp.bonjour.lan = 0 0 631 mfp.printer TXT TestPrinter._ipp._tcp.bonjour.lan txtvers=1 qtotal=1 rp=Print ty=Toshiba MFP adminurl=http://mfp.printer note=Shared MFP priority=0 product=(Toshiba eStudio 351c) printer-state=3 printer-type=0xC0B0DE Transparent=T Binary=T Fax=F Color=T Duplex=T Staple=F Copies=T Collate=T Punch=F Bind=F Sort=T Scan=T pdl=application/octet-stream,application/pdf,application/postscript,image/jpeg,image/png,image/urf URF=none
