Symptoms

The print dialog in the screenshot below will show the error "Encryption credentials have expired." If you find a similar issue, the solution can be found below.

Diagnosis

On Mac OS devices, you will be unable to print or scan. The above dialog will appear every time you try either action.

Solution

This error typically occurs when the Embedded Web Server (EWS) has an expired certificate:

1. Open HP App:

   • Search for and open the HP App. If you don’t have the application, download it for free from 123.hp.com or your app store.

2. Select Your Printer:

   • From the homepage of HP App, choose your printer’s name or image, then go to Printer Settings.

3. Access Advanced Settings:

   • Click on Advanced Settings or Embedded Web Service (EWS).

4. Complete Login Information:

   • If prompted, fill in the necessary login or certificate information to access EWS.

5. Navigate to Security:

   • Select Network Summary. From the General Network Summary page, scroll down and select Security, then click on Certificates.

6. Generate a New Certificate:

   • Choose Configure, then Create a New Self-Signed Certificate, and click Next.

7. Finalize the Update:

   • Click the Finish button and exit from EWS. The printer will generate a new certificate, defaulting to a validity of 10 years from the current date.

Use the HP printer Embedded Web Server (EWS)

Workaround

Resetting the certificate is the preferred method of resolving this issue. If resetting the certificate does not work, please try adding the "AirPrint" driver following the directions from the below post. Note do not select the "Secure AirPrint" option as this will cause the expired credentials error to appear.

You will be selecting the "AirPrint" option sending your print data unencrypted. This has to be done on all affected Mac devices to enable print or scan to work.

Thanks! I had to try all three methods before I got the right one, and pages are not always so obviously what I wanted, but eventually I reestablished a viable Certificate! I can now print!
