Microsoft vowed that Office for iPad users wouldn't always have to track down a PC just to print their files, and it's making good on that promise with a slew of app updates. The tablet-sized versions of Excel, PowerPoint and Word now let you make hard copies of documents so long as you have an AirPrint-friendly printer on hand. The move tackles one of the biggest gripes we had with Office when it launched last month; it's at last possible to skip the computer entirely when producing that class report or family budget.Printing isn't the only upgrade in store. Excel now has auto-resizing for columns and rows, while PowerPoint gets Keynote-style guides that help align all the graphics just so for your big presentation. All told, these refinements are huge if the iPad is your productivity center -- head over to the App Store source link to start updating.
