AirPrint is a new feature introduced in iOS 4.2 offering wireless printing over a wifi network. If you have a iOS 4.2 device and thinking of testing/using its AirPrint service in Windows 7 go through this detailed article. This installer works on Windows XP, Windows Vista and Windows 7. I tried this out in Windows 7 x86 version and found perfectly working.
Initially set your printer as shared in Windows and be ready with iTunes 10.1 installed in your machine. Now, download the AirPrint ZIP package from here.
After downloading unzip its contents to C:/Program Files/AirPrint. (Unpack the archive into C:/Program Files/AirPrint (x86) folder if you are using Windows 7 x64 version)
For x64 version:
sc.exe create AirPrint binPath= “C:\Program Files (x86)\AirPrint\airprint.exe -s” depend= “Bonjour Service” start= auto sc.exe start AirPrint
For x86 version:
sc.exe create AirPrint binPath= “C:\Program Files\AirPrint\airprint.exe -s” depend= “Bonjour Service” start= auto sc.exe start AirPrint
After installation Windows Firewall will prompt you to allow access for AirPrint. ‘Allow’ access. Now you are ready to use your iOS 4.2 AirPrint with Windows 7.
