HP 4655 WiFi Duplex print fail

[Valin]

Problem: WiFi Duplex print option on HP4655 fail:

1. HP 4655 WiFi Duplex print is not an option whereas direct USB connected works fine.

2. It can be seen that the box on the left (which is USB direct connection) shows "Print on Both Sides".

3. Whereas the Network connection on the right shows "Print on Both Sides Manually".

4. It appears there is no way to make it print Duplex via WiFi.

Driver is up to date and I tried reinstalling it with no change.

Besides this hiccup the printer is excellent.

Hi,
Make sure the Automatic Duplexing option is enabled:

Enter Control Panel > Devices and Printers.
Right-click the HP Officejet 4650 series (Network) printer icon, then click Printer Properties.
Click the Device Settings tab.
Set the Automatic Two-Sided Duplex Accessory as installed and click OK to save the change.

Now Automatic Duplexing should become available.

Regards,
Shlomi

Thank you for help Shlomil!  But ..

"Enter Control Panel > Devices and Printers.
Right-click the HP Officejet 4650 series (Network) printer icon, then click Printer Properties.
Click the Device Settings tab."

Sadly there is no  'Device Settings tab' .. just General or Settings or Details or Events 

none of which have 'Automatic Two-Sided Duplex Accessory '

Thanks for the information @Valin,

Please carefully follow my steps and open the Printer Properties option for your printer icon under Devices and Printers, what you describe seems like the Properties option for your printer from the Device Manager.

Thank you for the reply but, see below, this looks to me like the right place, but without the option you recommend:

under Devices and Printers - Printer Properties - option printer icon  ...

This is not the right place, this is the Properties window while you need the Printer Properties window:

Once selecting Printer Properties (as marked in green above), you will see the Device Settings tab available.

Thank you again for your help Shlomil, I really appreicate you giving me your time.

Thanks to your last note, I now have the correct Printer Properties tab and selected Device Settings  But ..

As you can see below there is no Automatic Two-Sided Duplex Accessory  you recommended, though it does have Automatic Duplexing Unit, but this is grayed out and is non-clickable ..
Any ideas?
Thanks again!

After reading "solutions" that did not work (for example full restore from internet download of software and drivers from HP website), I again uninstalled everything and reloaded from the original CD shipped with the printer and bingo it worked again.

HP's own online software is buggy but the CD was fine!
