handyPrint, previously AirPrint Activator, is a small application that will enable AirPrint, a hidden feature to allow your shared printer to be visible on your iOS 4.2+ devices, in Mac OSX 10.5, 10.6 and 10.7. Run handyPrint on your Mac to share local and network attached printers to an iPhone, iPad or iPod Touch running iOS 4.2 or newer. handyPrint listens to all local network printer advertisements and make them available via AirPrint. You only need to run handyPrint once: once it has been turned on, it will remain on even after a reboot.
