Sure that helps but as soon as I reboot my computer it goes right back to double sided printing.  It's a little inconvenient having to change it each morning!

You can easyly solve this with the following procedure:

Open your Windows Group Policy Editor, chose "New Group Policy", go to UserConfiguration->Settings->Windows Settings->Registry. Right click "Registry", chose "new-> registry assistent", local computer, go to

[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\10.0\AVGeneral]

"iDuplexMode"=dword:00000002

(mark only "iDuplexMode" !)

and click "finish".

Doubleclick that new entry down till you see "iDuplexMode", double click it too, and change the REG_DWORD value into "1" (decimal). At the very top I also chose "replace" under "action" (not sure if really needed)

Close the GPO editor and link that newly create group policy to you domain or OU or whatever.

You can make a "gpupdate /force"at a client to see the reg entry changing from "2" (= dublex) to "1" (=non duplex).

Reboot your clients or just wait your personal "gpupdate time period".

Thanks Adobe for that setting!

BTW: You can also config that with the "Adobe Customization Wizard X" and save it in a .mst file to roll out your installation with Active Directory software distribution or your favorite tool. Unfortunatly - as it is an entry in HKEY_CURRENT_USER - this hive is only load after log in and it is not present during bootup installation, so your setting gets lost.

You can do the same for Adobe Acrobat X, if you need. The Key is:

HKEY_CURRENT_USER\Software\Adobe\Acrobat\10.0\AVGeneral] 

"iDuplexMode"=dword:00000002

Have you checked the correct reg key? It works fine here for ~ 50 computers with W7 and W XP.

HI,

Although this work around has resolved defaulting to duplex, it does seem to directly interfere with the Printing Preferences of the printer.

In our case, We have 2 Print Queues associated with each of our physical printers:-

Printer1

Printer1-Bill

The latter has printing preferences set to print double sided and various other settings.

Normally a user would print to the Printer1-Bill printer and the printing preferences of the copier would handled the paper accordingly, however if the duplex option is turned off within Adobe 10.1.2, it also turns them off the settings in the printer preferences, meaning users then have to either switch duplex on in Adobe (which leaves it on), or manually modify the printer preferences of the printer.  Neither are acceptable.

Any assistance is appreciated but for now we have to remove the iduplexmode registry key and users will need to ensure duplex is turned off when not required.
