Likely the driver on your PC has forgotten that the printer has a duplex module. On your PC

go to control panel>devices and printers and then right click the icon for  your printer and select printer properties from the drop down menu. Then click on device settings tab and scroll down till you see installable options and find duplex and make sure it shows as installed. If not click on it and change to installed.

Thanks for the info but the actual problem was not absence of duplexing but not auto duplexing which this printer is capable of but would only duplex manually.  Ran HP Print and Scan Doctor and removed the device.  Once I reinstalled it started working correctly.  Thanks again for taking the time to answer as it's important that users support each other.
