Printer suddenly no longer set up for automatic double sided printing

[Y4L]

Last week I could print double sided automatically from my laptops but now I can't. I can only manually print double sided and cannot open the function to change it in the printer settings. It just says "no" in settings next to double sided. But I can print double sided when using my iphone.

Hi Y4L 

A) Printer settings Duplexer:
Search Windows for 'devices', and then click the Devices and Printers control panel setting in the results.

Right-click the icon for your printer model, and then
click Device Settings tab
Installable Options > Duplexer: installed

If not, change to installed.

B) Automatic Two-Sided Duplex Accessory:

Enter the Control Panel > Devices and Printers.
Right click the 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.

If the Options > Duplexer or Duplex Accessory is not displayed, then download only HP Full Feature Software 

1. Uninstall HP printer software, and then remove the printer from your Devices list. 
2. Restart the PC
3. Close all programs
4. Open up the run command with the "Windows Key + R" key combo > in folder Downloads double-click on the EXE
5. The installation was completed successfully, now you must ...
6. Restart the PC again
7. Now the installation is complete.

Document error messages accurately, even better is to take a screenshot of it and upload here.
