Since its December 2011 debut, wireless printing software Printer Pro has never gone free, excluding a limited one-day promo last April.
That changes today as Apple's editors have now marked the iPhone and iPad application down to $0 (regularly $6.99), listing the app its Free App of the Week in the App Store's ongoing weekly promotion.
Created by Ukrainian developer Readdle, Printer Pro has been downloaded two million times. It's a great app that lets you print attachments, documents, web pages and more right from your iPhone or iPad to any printer.
It automatically finds and connects to a printer on your Wi-Fi network. You can even connect to a USB printer if you install a free helper desktop app on your Mac or PC.
