Promises more than it delivers – Printer Pro by Readdle Review

I have had this app for over a year. It won't work with my older printers and on the compatible ones it the output is not always true to the original. The biggest disappointment is that most of the times that I try to use it I discover that it won't do what I want. So I keep it around but I'm not sure why.
