Won't Work with Normal Printers – Printer Pro by Readdle Review

It found the printers on my network. However, NONE of the printers would work with the App. All of the test pages either didn't come out or failed. All of these are non-airprint printers. The only thing the app suggested to do was install an extra piece of software on my desktop...which I don't have! Really disappointed given all these other reviews. There are other products that I have tested that work much more effectively.
