Vista - HP6980 will not Automatically do Duplex with Duplex Hardware

I have an HP6980 printer with the automatic duplex attachment. It worked
fine with XP but under Visat I can not get it to print duplex using the
duplex hardware.

The software lets me select auto duplex but it always does manual duplex.

Has anyone else seen this.

I use a USB connection to the printer as the network connection under
VISTA did not always work.

Have you installed the fully featured HP software:

Microsoft Windows Vista

If you are using the driver that may have come with VISTA and that would be
installed if the printer and it's USB cable were attached to the PC when
you installed VISTA that very likely does not include software for the
duplexing whcih from the manual seems to be in the HP Toolkit, that I know
comes in the Fully Featured Software for my PS8250

Looking at the manual for your 6980 I wondered if having installed the
duplexer you had enabled it after installing it in VISTA?

Enable the duplexer

Follow these step to enable the duplexer:
1. Open the printer Toolbox.
2. Click the Configuration tab.
3. Click Automatic Two-Sided Printing Module or Auto Two-Sided Print
Accessory with small paper tray, and then click Apply.
4. Click OK in the confirmation box that is displayed.
5. Click the X in the upper-right corner to close the screen.
Note After the duplexer is enabled, it is not necessary to re-enable it
every time you print.

Note also:

The two-sided printing accessories only support certain paper types. For a
list of supported paper types, see the documentation that came with the
accessory.

If a two-sided printing accessory is not attached to the printer or you are
printing on an unsupported paper type, use manual two-sided printing.

Although I would not expect this to be different between XP and VISTA.
