A MacForums member posted emailed to Steve Jobs to enquire about the said to be pulled off of AirPrint from Mac OS X 10.6.5.
Good Morning, Mr. Jobs: As a release-day purchaser of an iPad, I was elated when you revealed iOS 4.2 would support AirPrint. Now comes reports AirPrint support has been pulled from 4.2. Between announcements/assurances of the white iPhone, and now the pulling of AirPrint, is Apple going to lose credibility and become known for announcing "vaporware"? Respectfully, <redacted>
AirPrint has not been pulled. Don't believe everything you read.
