Why can't I print two-sided since going to Adobe Reader DC?

I looked this thread up just because I was interested in what the answer is.

Disappointing there's nothing.

BUT this one from about three years ago describes a workaround using printer settings that reminds me of something I successfully did months or a year or two ago. No option to print duplex in 10.1.9

Sorry, Adobe, I have no intentions of installing Reader DC so I can thls this poor soul any more. MY solution was to install Reader XI. Among other things, it's NICE to "save as" in a different location by just clicking a menu and going down a few rows, rather than clicking a menu icon, then clicking something about commands, and THEN moving my mouse ALL THE WAY DOWN diagonally across the window to finally find "Save as...".

Yea, you really improved the product with the Windows 10 style interface.

Sorry, I've forgotten the answer to this one.

WHY can't you choose so many of your beloved functions from the older native on your PC Adobe Reader? Because it appears that Adobe followed Microsoft down the Windows 10 rathole of removing features, hiding features that used to be quickly findable in those old-fashioned menus, and multiplying the number of mouse-clicks you are forced to do in order to perform the most simple tasks.

I'd love to give you more, but right now all I can suggest is looking in other places you are not used to, such as printer properties or page type in the print dialog boxes.

I think totally losing the ability to scale printouts (like 91% of "actual" size) is why I abandoned the DC product. Now looking for a legacy download of the NON-Document Cloud version. Re-installed the OS last night...
