Unsigned Printer Driver

[jpusche]

Recently updated WIndows 10 and my laptop can no longer user my printer to print or scan documents.

When I look at the printer driver, there is an indicator that the driver is not digitally signed, which is preventing it from properly installing.

I have tried multiple times to uninstall and reinstall the Full Feature Software from the HP website with no luck.

I have also tried to disable the driver-signing enforcement in Windows 10 to allow for the driver to install. This did not work either.

Need to get this working as it is the only printer in the office.

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand the device isn't installing the printer driver due to the message - "unsigned printer driver",

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

• Have you attempted to change the user access control (UAC) settings on the user account, disable it and check if this works?
  • If not, please do and let me know how it works.

While you respond to that, here's what you need to do:

I recommend you delete the driver at the root level and retry, follow the steps below: 

1.) In Windows, search for and open Programs and features 

2.) Select your HP Printer 

3.) Select Uninstall 

4.) In Windows, search for and open Devices and printers 

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose `Delete' or `Remove Device' 

6.) Open up the run command with the "Windows key + R" key combo. 

7.) Type printui.exe /s and click Ok. (Note: there is a space in between "printui.exe" and "/s") 

8.) Click on the "Drivers" tab 

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 

10.) Select Ok 

11.) Select Apply and Ok on the Print Server Properties windows 

12.) Close Devices and Printers 

Then, use this link to access the HP website, find the drivers compatible with your windows and install it: Click here
