iOS 4.2 hasn't been officially released yet, but some enterprising developers, Steven Troughton-Smith and Patrick McCarron, have already found a way to re-enable AirPrint functionality in Mac OS X 10.6.5. Apparently, three files from earlier developer builds of 10.6.5 were removed or altered for the final public release, and it's these files that are essential to restoring full AirPrint functionality.

AirPrint is something that I was really looking forward to in the next version of iOS. While this functionality
appears to have have been pulled from the iOS4.2 GM that was sent to developers, and there are rumors that the functionality has been pulled permanently, others are reporting that Steve Jobs
responded to this rumor with "Don't believe everything you read."
In the mean time,
this article give you a step to re-enable this functionality if for some reason it does not return as quickly as you want. I love the fact that it comes along with a disclaimer by TUAW:
The usual caveat: This procedure involves a moderate degree of peril, and TUAW cannot help you if you mess up your system. Proceed at your own risk.
