EPSON Artisan 810 Two-Sided Print Option Grayed Out
Hello,
I have written a document in Pages and am attempting to print double sided using an EPSON Artison 810 all-in-one as I have used it in the past. The media type is set to plain paper/bright white paper, the paper size is US Letter (or 8.50x11.00) and Artisan 810 is the selected printer. As far as I can tell, the Two-Sided option should be working, however every time I try I get the following screen:
Does anyone have advice on how to get this to work?
