To install AirPrint for Windows, first download iTunes 10.1, and install it on the computer. Check the printer's settings, and ensure it is listed as a shared printer and that both it and the operating system share a Wi-Fi connection. Download the installer from the Jaxov website, right click Setup.exe, and run as administrator. Follow the prompts as the program prepares to install, and click Next to continue. Hit Install and, when prompted, allow AirPrint access to the network.
If the easy installation method does not work, enable AirPrint for a Windows 7, Vista or XP 64-bit operating system, by going to C:\Program Files (x86) and making a new folder; call it AirPrint. If a 32-bit operating system is in place, go to C:\Program Files and do the same. Download the AirPrint .zip file from AirPrint Activation's website, and unzip it into the newly created folder.
Go to Run and type the letters "cmd" into the drop-down box to open the command prompt. For a 64-bit system, type in the following command: "sc.exe create AirPrint binPath= "C:\Program Files (x86)\AirPrint\airprint.exe -R _ipp._tcp,_universal -s" depend= "Bonjour Service" start= auto sc.exe start AirPrint". For 32-bit systems, type in the same command without "(x86)."
When the Windows firewall asks for AirPrint to have access to private and public networks, grant the request. Any document or email may now be printed wirelessly by clicking the print button when linked to a Wi-Fi connection.
