AirPrint now [officially] supports 100 printers
Apple is well known for making things easy, products that just work. AirPrint, the company’s wireless printing solution, is no exception. Unless, of course, you don’t have a compatible printer. However, in addition to the 100 printers officially supported, AirPrint Activator makes it quick and easy to use almost any OS X compatible printer.
Compatible idevices: Any iPad, iPod touch (3rd generation), iPhone 4, iPod touch (4th generation), iPhone 4S, iPhone 3GS running iOS 4.2.x or higher
Again, the good news: Apple’s official AirPrint 101 page lists over 100 compatible HP, Canon, Epson and Lexmark printers. That’s up from just 27 printer models back in June.
And, the rest
As you can see, my relatively geriatric Kodak 5300 AIO plays just fine with AirPrint once Activator has done its thing, which is a major convenience for iPhone toting wife that prints lots of coupons.
There are AirPrint Activator versions available for PPC and Intel Macs running OS X 10.5 or higher.
