Cannot get Epson printer to stop printing two-sided
I have gone to Epson's User's Guide for printer and am not having any success. I have deleted the printer and added it back. When I go to print a document I get all sorts of printing options but none of them offer to stop two sided printing. I have not been able to update my iOS and am operating on the macOS Mojave 10.14.6 version.
I have Googled how to change the settings and hit the Apple Form but not getting the answers needed. If anyone can help, I would appreciate it.
