I'm still very much experiencing the same issue, always when using Adobe on Mac. Double-sided printing is not an option within Adobe Acrobat DC, I click 'printer' leading me to my regular printer application and a bugged. I have nothing else to say that has not been said already. This issue has prevalent for years. I don't understand the continued confusion.
