Hi,
I am using Adobe Acrobat Pro version 11.0.10 on a Mac running OS X 10.10.1 with a latest updates installed. I would like to make Adobe Acrobat Pro to print double sided (Duplex) by default. In a printing dialog there is a checkmark called "Print on both sides of paper" which does the trick, but only temporary. I have to check this option each and every time I want to print duplex.
What I tried is to edit preferences file located in /user/Library/Preferences/com.adobe.Acrobat.Pro.plist and added key "DuplexMode" under "AVGeneral" and I didn't worked. I did some research online and I found out that previous versions of Adobe Acrobat Pro and Adobe Reader had no problems with defaulting Duplex option, I even installed Adobe Reader 10.1.2 myself to try and it worked like a charm. Please let me know how can I default Duplex printing on a newest version of Adobe Acrobat? It seem like a bug to me, if it is, let me know when can I expect a software update to fix this? Thank you
