As we’ve mentioned, AirPrint Activator is a free way to print from an iPhone/iPad to any Mac-connected printer (even a PDF if you follow our instructions). Now a complete re-write was done in version 3 of AirPrint Activator was just finished to make it compatible with iOS6 and Mountain Lion 10.8.
It works great and is still free.
The best solution for Windows users continues to be FingerPrint 2 for $20.
