Airport Extreme and Airprint
Is AirPrint enabled for Airport Extreme connected printers? I'd like to use the feature with my iPhone4 without buying a new printer.
iOS 4
Check out Airprint Activator (http://netputing.com/airprintactivator/). It is a free tool that will allow you to use your current printer hardware, even when it is connected to your airport extreme. You need to follow the instructions on the page, or it will not work correctly. Also, the computer that you install the software on must be turned on for your printer to work over your airport extreme. You should then be able to print from any iOS device. Hope that helps!
