If AirPrint made printing from iPads and iPhones easy, DocPrinter for iOS makes it downright simplistic. Created by business app developer EuroSmartz, DocPrinter makes it easy to browse, email and print files, photos and web pages stored on the device or in Apple iCloud, Dropbox and Google Drive. For $4.99, DocPrint prints to all printers via Ethernet, Wi-Fi, USB and Bluetooth. It also can print remotely via 3G/4G connection without additional software. After downloading, a simple menu reveals choices of what to print. It even stores files on the device to print when it's needed.
