Apple Inc.'s iPad, iPhone and iPod Touch can handle many tasks once performed by personal computers. People can check e-mail, surf the Web, edit photos and compose documents. Although the gadgets can connect with computers to transfer files, they don't have ports for connecting with printers or USB drives.
The update, iOS 4.2, includes AirPrint for wireless printing. Apple says it will automatically find printers on local networks and send text, photos and graphics for printing over Wi-Fi.
Apple says AirPrint will work with a wide range of printers, from inkjets to laser printers.
