I'm hoping it shows up for iOS 4 this summer. Really, Bonjour discovery of printers with a simple "print" menu or gesture summoning up a list of available printers doesn't seem beyond Apple's UI paradigm or the underlying tech. Doesn't seem to add much complexity, doesn't run athwart of any of Apple's pet bugaboos, so I'm puzzled as to what the deal is.
All I can think is that they're planning similar functionality for the iPhone and are going to roll it out for the next iPhone OS major update.
Thanks addabox. That was precisely my point as well.
God help you if you ask this question in the Apple Official Support Forums. And the emperor still has no clothes.
