Jan 4, 2011, Use of AirPrint in 123 Color on iPod touch (2nd generation) and iPhone 3G running iOS 4.2.1
The Print Picture option appears only on devices which support AirPrint. Apple did not extend the AirPrint feature to 2nd generation iPod touches, original (aluminum) iPhones, or iPhone 3G. With the iOS 4.2.1 update, Apple added the AirPrint feature to iPad, iPhone 3GS, iPhone 4, and 3rd and 4th generation iPod touches. It is on these devices that the Print Picture option appears in 123 Color and 123 Color HD.
