The iPad will allow programs to run in the background while users do other tasks.

Apple Inc. released new software on Nov. 22 that lets users of its iPhone, iPod Touch, and iPad devices print wirelessly over Wi-Fi networks. The software addresses what has been a key complaint about the iPad to date—that users can’t print their documents from the tablet—and ed-tech observers say it could help spur more widespread use of the device in schools.

Apple first described some of the new features in iOS 4.2, the latest operating system for the Apple gadgets, at a media event in September.

The iPhone, iPod Touch, and iPad don’t have ports for hooking up with printers, which makes the AirPrint feature one of the biggest advances for all of Apple’s gadgets.

With the new software, the gadgets can find printers on home or school networks, then send text, photos, or graphics directly to the printer over Wi-Fi.

To start, iPads, iPhones, or iPods with AirPrint will only work directly with certain Hewlett-Packard Co. printers.

The software update also includes AirPlay, which lets iPhone, iPad, and iPod Touch users send video, music, and photos directly from the gadgets to the TV screen through the company’s Apple TV set-top box. Someone who is watching a movie on the go on an iPad could walk into his or her living room or dorm room and switch to the TV with a few taps.

Apple also said special AirPlay-enabled speakers for streaming music will be on sale in the coming months.

In addition, Apple said it is making its Find My iPhone application available without charge for owners of the iPhone 4, the iPad, and the latest iPod Touch model.

The app helps people find their missing device on a map; users also can remotely lock or delete data from a lost device, which could help with data security on campus.

The update brings many features already available for iPhones and the iPod Touch to the iPad, including a form of multitasking, or the ability to keep some programs running in the background while doing other things. For example, users will be able to start up the Pandora music program and keep listening while switching to another application. The update also makes switching between programs faster.

With the new software, iPad users also can consolidate multiple eMail accounts into one inbox, play games against other Apple gadget owners, and rent TV episodes from the iTunes app.
