Hello, I recently bought Readdle's Printer Pro based on great App store reviews and other sites recommendations, but I can't get it to work for ANYTHING. I have an Epson NX420 printer, and the initial print was fine, and I did the alignment thing correctly (three times), but when I print any document (PDF, Pages, Word from Dropbox), it prints, but it is shrunk. I have toggled the option: "original size" or "zoom to fit" whatever it is, but the printouts are the same. I email their tech support and they said check printer margins, and then never replied. I don't think the margin this is the issue since it is set to it's defaults and prints from our Windows and Mac computers perfectly. Do any of you have the app and have this problem?
