How to update printer certificate?

Hi @Rockyknows 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for sharing the details! 😊 Updating the printer’s certificate can help keep network connections secure, especially when printing over Wi-Fi or via remote services.

Here’s how you can move forward with refreshing or importing a new certificate for your HP Color LaserJet Pro M252dw:

🔒 Steps to Update the Printer's Certificate

 

✅ Step 1: Access the Embedded Web Server (EWS)

• Make sure your printer is connected to the network.
• Open a web browser on your computer.
• In the address bar, type your printer’s IP address (you can find this by printing a configuration page from the printer).
• Press Enter to load the EWS interface.

✅ Step 2: Sign In

• Log in using the administrator credentials (default username might be blank, and default password could be "admin" unless changed).

✅ Step 3: Navigate to the Security Settings

• Go to the Networking or Security tab depending on your firmware version.
• Look for Certificates or SSL/TLS Settings under that section.

✅ Step 4: Manage the Certificate

• You’ll see options to:
  • Create a self-signed certificate
  • Import a CA-signed certificate
  • Renew or replace existing certificate

✅ Step 5: Install or Update

• If you're installing a new certificate:
  • Choose "Import certificate"
  • Upload the .crt or .pem file as provided by your Certificate Authority.
• If renewing:
  • Click on the existing certificate and follow prompts to generate or upload a new one.

✅ Step 6: Save and Restart

• Click Apply/Save to finalize.
• Restart the printer to apply the changes.

If you encounter trouble accessing the EWS or the certificate options appear greyed out, a firmware update might be needed first. And I know—this kind of thing can be tricky and a bit tedious. 

If you’d like, I can walk you through that part step by step. Happy to help every inch of the way! 💪😄
