double sided printing with Mojave
Why can't I print double sided?
Using Mac Pro with Mojave, Epson XP-830 which is capable of printing double sided.
On my pop-up print menu, under Layout, I cannot choose Two-sided printing - the word "off" is greyed out and I cannot select or deselect it. (see screenshot)
In System Preferences Printers, Two sided or Duplex printing is not listed as an option even though my printer is capable. (see screenshot)
I have been able to print double sided from this computer with this printer in the past. I am still able to print double sided from my iPad.
Is this a glitch in Mojave? Is there anything I can do to double side print from my computer?
