Just purchased PrintCentral for use with my Epson Workforce 600 printer. It prints the 2 line text test fine, but that's it. Everything else is just a line of characters or gibberish. The developer's website is no help as they want you to install software on a computer to print to the printer through the computer. I had heard this app was greatcand would work. Can anyone help or have I wasted $10.00?
