Printing never "just works," does it? There always has to be some wrench thrown in. We were hoping Apple was about to solve some of that with AirPrint, but at the last minute it left out the Mac printer-sharing functionalities that were supposedly going to arrive with Mac OS X 10.6.5. That means as of right now the only way to do AirPrint with the yet-to-be-released iOS 4.2 is to buy one of those fancy new HP printers with the AirPrint-compatible ePrint functionality. We're guessing Apple is just giving this feature a little more time in the oven
