Starting with , Apple smartphones have been AirPrint-enabled, and most recent printers from major printer brands, including but not limited to Brother, Canon, Dell, Fuji/Xerox, HP, Lexmark, Ricoh, and Samsung, are AirPrint-compatible. (Apple has a omplete list of available.) AirPrint printing functionality is the same no matter which model iPhone you own (provided that it's 3GS or later); it will work with iPads and iPods touch as well. With AirPrint you can print documents from Apple programs, such as Photos, Safari, Mail, and iPhoto, as well as other email clients, Office documents, and many third-party apps.
One of the most anticipated features of iOS 4 was its wireless printing feature, dubbed AirPrint. The service allows users to print directly from iOS devices. AirPrint was supposed to utilize any printers shared by Macs on the same local network as the iOS device. While this feature was cut before release, to enable it. Despite AirPrint not being as powerful as it once was, HP has not stopped adding new AirPrint printers to the fray.
When Apple first included its AirPrint printing utility—which allows printing from an iPhone or iPad to a compatible printer on the same Wi-Fi network—in an iOS upgrade in late 2010, only a handful of HP printers were supported. Fortunately, AirPrint compatibility has greatly expanded in the past few years, and most of the new Wi-Fi-enabled printers we test are AirPrint compatible.
An Apple spokesperson tells me that there is "no difference between the way AirPrint would work on a printer that supports Apple's new AirPrint printing architecture (like ePrint printers from HP) or one that is connected to a Mac or a PC."
