iOS 4.2 Beta Drops, and Apple Announces ‘AirPrint’ 

The first developer beta of iOS 4.2—the first 4.x release that's compatible with the iPad—is now available to registered iOS Developer Program members. The new software will include a new wireless printing technology called 'AirPrint'; iOS devices (including iPhones and iPads) will be able to print to shared printers attached to their Macs/PCs, or directly to wireless printers (such as some new HP models shipping this Fall) that support the new protocol.
