I have PSE 11 on a Windows 7 PC printing to an Epson XP850. After months of successful printing the printer kept reporting a communication error and would not print from PSE but does so from other programmes. It looked as if PSE all of a sudden wanted to print to the old R800 printer which had been replaced. I uninstalled the R800, still no joy. I uninstalled and re-installed the XP 850 and the problem persists. The error message from PSE 11 is "the saved printer information is not compatible with this version of PSE or the saved printer is no longer available". I would uninstall PSE 11 and re-install, but I don't want to lose all the Organiser information. Can anyone offer any helpful suggestions? It would be a great help and very much appreciated.
