Printer Driver Officejet 4500 G510m install error digital signature issue

[Mike-T2]

Printer not recognized by Windows 10. Found driver but the driver cannot be installed because it is either not digitally signed or not signed in the appropriate manner. Contact your hardware vendor. 

Was working a week ago. Not now. 

Adding the printer through windows set up for adding a printer. This message above is provided by windows.

Thanks for picking this up. I followed your steps below. One note: at the step Look for HP Printer driver. If you see it click on it and click Remove at the bottom. Need to remove the driver and package for complete removal. 

I have completed all the steps and installed the HP Smart App via the add printer steps. The printer is recognized and listed and no longer offline, however, when printing the document goes into error status and nothing prints. 

Interestingly enough, I am able to scan from the device which means windows is communicating with the device. I just can't get anything to print. Ran through the troubleshooter 2x but no luck. 

In the HP Smart App these are a few of the items in the status:

Status: Printer status unknown

Installation Status: Not installed

Connection Type: Network

Connection Status: Active.

Thoughts on next steps?
