I'm writing this because of a request I got yesterday about setting up AirPrint on an XP box. It got me thinking... It's soon going to be a year since this feature come out, and yet we are still stuck with official support for a number of HP manufactured devices. Various 3rd party hacks and solutions popped up, but I find it odd that Apple has introduced nothing, even with the release of Lion (which broke stuff). I'm not looking for a technical solution, but was wondering why this feature is being left to whither on the vine. The only possible reasons I can think of are a patent or license issue (probably held by HP), or they made an exclusivity arrangement with HP for a certain time period in order to get native support for it on some printers. I'm starting to lean heavily towards that second reason. Why else are no other printer manufacturers releasing compatible printers? I wonder what will happen when the next version of iOS comes out and we hit a year after the AirPrint debut.
