Because multicast traffic is usually not routed across subnets, it requires Apple TV devices and AirPrint printers to be on the same IP subnet as the iPhone and iPad devices and Mac computers that use them. For small networks, this approach is the norm.
Does AirPrint work on different subnets?
For AirPrint to function, both IPP and Bonjour (mDNS) protocols must be enabled. The device that submits the AirPrint job must be on the same subnet as the printer. To allow devices to print from different subnets, configure your network to pass multicast DNS traffic across subnets.
How do I AirPrint to another network?
