Guys, it's called AirPrint and Apple advertises it quite visibly. It's one of the major features of iOS 4. You can see an extensive tout for it on Apple's website here http://www.apple.com/ipad/features/airprint.html http://www.apple.com/ipad/features/airprint.html All of the printers that support AirPrint are made by HP. AirPrint is really just an adapter on top of HP's proprietary ePrint. I believe ePrint even lets you send documents to the printer over email from a computer or any other device. http://h71028.www7.hp.com/enterprise/us/en/ipg/HPeprint-solution.html http://h71028.www7.hp.com/enterprise/us/en/ipg/HPeprint-solu... Google Android also has an adapter to directly print to HP's ePrint printers through Google's Cloud Print http://www.hp.com/united-states/campaigns/hp-eprint-google-cloud-print/ http://www.hp.com/united-states/campaigns/hp-eprint-google-c... Normally Cloud Print for Android (or any other device) works by running a print server which is bundled with the Chrome web browser on a Windows PC connected to a normal printer. Instead with ePrint the network print server exists on the printer itself so you can send documents to it directly. Obviously, the HP TouchPad works with ePrint natively out of the box. So all of these mobile operating systems are designed to work with the same line of printers which are all made by HP. Technically, Android can work with more printers assuming you want to rely on a Windows box to act as your print server.
