Duplex Print Does not Work in Windows 7
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.
