No Automatic Duplexing in Windows 7

[CA313607]

I have a Photosmart C7180 printer with the automatic duplexing attachement.

This hardware feature is recognized by the Windows XP and Vista drivers and

thus there is the option to do automatic duplexing in the preferences menu.

I downloaded the Windows 7 driver from HP's web site a week ago and am

disappointed to find out that I have lost this feature; only manual duplexing

is offered in the printer preferences.  I already checked the "Printer Services"

menu and there is no "Configuration" tab where the Automatic Two-sided

Printer Module is expected to be found.

OK, I have stumbled upon the answer to my own question.  In "Printer Preferences" under XP and Vista,

choosing  "Features -> Printer Services" opens another window which is titled "HP Photosmart C7100

series Toolbox".  The last of three tabs is called "Configuration" where the Automatic Two-Sided Printing

Module appears with a check box to enable/disable this feature.  This "Configuration" tab is not present

in the Windows 7 version of the driver (13.1.0).  Instead, one must go the the Windows Control Panel,

Devices and Printers, right-click on the appropriate printer, e.g., "HP Photosmart C7100 Series", and

choose "Printer properties".  In the "Device Settings" tab, you will see the Duplex Unit as an installable

option.  In my case, this option was listed as "Not Installed" even though it was attached to the printer.

Changing the status to "Installed" and applying the change caused the automatic duplex option to appear

in the "Printing preferences" menu.  While in the "Device Settings" tab, you'll also want to enable the

Photo tray option for the appropriate size of photo paper.
