@networknerd said in Server 2016 Redirected Printer Change: That's a new one I have not seen. We used Epicor ERP 10, and in that product I did see issues with RemoteApp where from time to time the user would not have a default printer selected in Epicor (sounds weird, I know), which would then crash any report they tried to print with an error that value of -1 was not allowed. Getting the user to change the printer to something in their list was the workaround. Thanks for capturing this. I bet it will help someone else and looks to be already doing so. YEah, that is what happens for this case, the RemoteApp shows the printer as a question mark. Once you go to File, Printer Setup and DoubleClick the printer then it is all good for the printer but all reporting shows in Portrait mode instead of Landscape mode.
