Acrobat X: Lost default duplex print

I too had the problem of not being able to print and not having a dialogue with the option to print on both sides. I found that this problem could be rectified in Windows by going to Control Panel > Hardware and Sound > Devices and Printers > Printer Properties > Device Settings > Installable Options > Duplex Unit: Not installed.

By clicking on Not Installed, a drop-down menu appeared with the option of Installed. Selecting Installed and then clicking OK fixed it.

Now when I print in Acrobat Reader, there is the option to "Print on both sides of paper."

The exact path in Control Panel described above may vary slightly, of course, depending upon your verison of Windows, but following it as much as possible (allowing for variations) should get you there. 

I have the same problem.... I am thinking of downloading Pro XI to see if it is any better.....

Below are screenshots from acrobat 9 and 10. I will try what bobwcsu says but it is really bugging me

thanks for any help guys

I have the same problem with Acrobat X Pro 10.1.3 on a Mac and a Brother HL-5340D laser printer.  I recently switch to using a MacBook Pro from a Windows laptop.

The duplex worked fine with the printer and X Pro under Win7.  It works fine with MSWord and other applications, it presents the printer presets drop down menu (one I have set duplex), as it does in other applications.

With Pro X I get the same print dialogue that conmolbry showed in his Feb 27, 2012 post.

To get it to print duplex I can: (1) click on the "Printer" button-it shows me the usual (not Acrobat) print dialogue, (2) click print in that dialogue (i.e. do not change anything) (3) that puts me back to the Acrobat diallogue, now when I click print I get two-sided printing. A little cumbersome and somewhat annoying, and wasteful of paper, when I forget do the extra step.

I have tried reloading the driver as instructed from the Adobe help site.

I'm having some strange issues too, fresh install.

It seems I have a document that will only print Duplex, even though Simplex is selected in the document properties and I can't seem to alter this on the print settings. Screenshots attached. I actually want to DISABLE double-sided / duplex printing.

Versions:

OS X 10.7.3

Acrobat Pro X - 10.1.2

Hi,

This is an already known issue at our end and we are tracking it through bug. We cannot ascertain when the fix for this would be released but please be assured that we are working on this.

We will update the forum once we have the fix available with us.

Thanks,

With the 10.1.2 update, Duplex has been turned ON by default for printing. Is this the version that you are using? Here is an article with further information on Adobe Reader/Acrobat 10.1.2 sets Duplex ON by default for printing. Apparently, the following key gets generated automatically when a user tries to print on a duplex printer and then closes Reader/Acrobat 10.1.2 in the Mac preference file setting:

[user]/Library/preferences/[com.adobe.Reader.plist OR com.adobe.Acrobat.Pro.plist]

The name of the key is DuplexMode under AVGeneral and it has Number/int data type.

1 = Simplex (no duplex)

2 = Duplex with Long edge

3 = Duplex with Short edge

NOTE: 0 (or key does not exist) = Duplex with Long edge
