Duplex print does not work in Windows 7. However, it works on your Windows XP computer with the same printer. This issue persists after updating printer driver.
In earlier versions of windows, there was an option to say that a duplex unit was installed under printer properties. Windows 7 has split properties into multiple items in the context menu.
To enable duplex printing in this kind of situation, please perform the following steps:
1. Click Start - Devices and Printers.
2. In Devices and Printers, right click on the printer, click "Printer Properties".
3. In the printer’s properties dialog box, switch to the Device Settings tab. In this tab, you should find an option to turn duplex printing on.

thanks for the useful tip... but why, oh why... why is Windows such a ***?!
This does not work for me on my HP Color LaserJet 2605dn in Windows 7 Professional SP1. Instead, pulling up the properties of the printer shows only two (2) tabs: General and Hardware. It would be really great to have some way to use to built-in duplex capabilities of this printer!

I did the same thing - be sure to look at the options carefully - select Printer Properties, NOT Properties
Thanks, while this was not the exact fix, it lead me near enough that I found the problem. I have a Xerox 6250DP and duplex (two sided printing) was not working. I discovered that I had installed a generic driver and I had to configure the driver to my printer model. Under the Configuration tab, I clicked Installable Options and changed the Printer Model. Hope this helps someone. I had a hard time finding an exact solution online.
