Print double-sided from Adobe pdf app

[Mbun2]

I have a pdf open in the Adobe app. I want to print it double-sided.
I'm on Sony Xperia tablet, Android version 7.1.1. Printer is Epson xp-400.h

If your printer supports dbl-side then you just mark that in the print screen options in preview.

I can print double-sided manually. In this app it's greyed out.
