Hi soleruler
My name is Jon and I am an independent technical adviser. Sorry to hear you are experiencing issues and I would really like to help you find a resolution.
Print double-sided in Acrobat DC, Reader DC
In Acrobat or Reader, choose File> Print.
Select Print On Both Sides Of Paper in the printer dialog.
Duplex printing
Click Print.
Print double-sided in Acrobat, Reader 10 or earlier
In Acrobat or Reader, choose File > Print.
Click Properties.
Click the Layout tab. This dialog varies printer to printer.
Make a selection from the Print On Both Sides pane. Depending on the printer driver, this pane can be called "Double-sided printing" or a similar name. If you don't see a Print on Both Sides pane, then your selected printer doesn’t support duplex printing. Or, the feature is turned off (see Verify that printer features are turned on).
Click OK, and then click OK again to print.
Hope this helps.
