PhiDeck: "In order to use AirPrint, you must have a wireless printer that is setup on the same Wi-Fi network as your iOS device that is supported by AirPrint".
That is a false statement, albeit widely repeated.
AirPrint, being a link-local protocol, requires that the iPhone/iPad and the printer be on the same IP subnet. There is NO requirement that the printer be connected to that subnet wirelessly. An Ethernet attached AirPrint printer works just as well, and reduces congestion of the wireless LAN.
Note that your wireless access point (WAP), whether stand-alone or built into a router, must be configured to bridge - not route - between the wired and wireless LANs in order for them to be on the same IP subnet. Since that is the default for home integrated WAP/routers, no special configuration is required for those units.
