Trouble with duplex printing on a Mac
I am using a Mac OS 10.13 and Adobe Acrobat Reader with an HP Officejet 7740 which supports duplex printing. When I choose duplex for a document the odd pages print right side up and the even pages print on the back but upside down. I have chosen Landscape and long edge binding. The duplex function works fine with other apps like Apple's Pages, just not with Acrobat. I used Terminal and CUPS to allow duplex printing, and have tried changing the other options such as short-edge binding. No matter what I try, the document prints all of the text perfectly except with the backs of pages upside-down. Again, all other apps print both one-sided and duplex on this printer in the right orientation.
