AirPrint Activator is a new tool by Stephan Muhl for those looking to use AirPrint with Windows.
Just download the one-click tool, install and activate AirPrint for Windows 32bit or 64bit. Then you have to have the printer in System Preferences (printer properties) to share. Already, all printer under Windows 32-bit or Windows 64-bit for IOS 4.2.1 and AirPrint available. Please note Step 3: AirPrint.exe must be enabled in Windows Firewall.
Works great. I have a 5 years old HP psc 1210 multidevice(printer,scanner) connected through usb to Pc with win 7. Of course i have wifi router at home and the Airpirint on iphone finds the printer and in works great!! Nice to have that feature.
I got the AirPrint installed and my pad sees my printer but when I pick one it insists on user name/password. As I run my main computer as admin with no password and my print shares are not supposed to be passworded I can't figure out how to fix things:(
