Printing from an iOS device is more complicated than it should be. PrintCentral Pro takes some of the sting out. To print, you launch the app, navigate to your Dropbox, iCloud or other documents, and print. Unfortunately, PrintCentral Pro doesn’t allow you to print documents directly from Apple's Pages, Numbers, and Keynote apps. The workaround is to email the documents to yourself and use PrintCentral Pro's email client to open the files. (I told you printing from iOS is too complicated.) Beyond printing, the app lets you convert files to PDF, zip and unzip files, remotely share files with Macs and PCs, save web pages as PDFs, and more. Note: PrintCentral ($5) and PrintCentral Pro ($9) are separate iPhone apps.
