So the iPad is growing up. It's not just your toddler's favorite toy or just your movie theater on the plane. The iPad has graduated to a full-fledged business necessity. One of the business apps getting rave reviews is PrintCentral. MacWorld gave it 4 out of 5 mice and it's been named the World's #1 printing app. With PrintCentral from Eurosmartz you can print direct to most wireless printers, or print to all printers (Bluetooth, USB, WiFI, Network) by installing the free WePrint software on your Mac or PC.
