Thank you for posting on the HP Support Community.

I have a few troubleshooting steps we could try to fix the issue:  

Let's try the root level installing setup.

Root level uninstall and reinstall printer drivers: 

• Go to Control panel – Programs and feature – Select all the HP Officejet Pro 8620 e-All-in-One Printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

If the issue still continues, install using Using the Windows Built-in Print Driver: Click here
