Apple AirPrint


AirPrint is a component of Apple Inc. iOS, version 4.2 or later, for printing via a wireless LAN (wi-fi),[1][2] either directly to any AirPrint compatible printers (such as HP’s entire ePrint range, Canon wireless models produced after September 2011,[3] select Brother models,[4] or to any Epson models produced after fall 2011[5]) or to non-compatible printers through a MS Windows, Apple Mac OS X[2][6] or GNU/Linux PC.[7][8] AirPrint does not require printer-specific drivers.
