Canon today announced 3 of its all-in-one Pixma printers will now support AirPrint from Apple. The printers are the MG8220, the MG6220 and the MG5320. Canon has posted a web page with more details. Some of the printers may require a firmware update to function properly.
AirPrint is the wireless printing technology Apple introduced in iOS 4.2, offering print services from the iPhone, iPad and iPod touch.
Originally, AirPrint was heralded to work with a variety of printers networked to a Mac, but when actually released AirPrint worked with only a handful of HP products.
Third parties have offered AirPrint functionality to get around the Apple restrictions. Printopia works quite well, and works with almost any networked printer. Another Bonjour-based printing solution is available from FingerPrint,
