Hi @JEDBD 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that your HP LaserJet printer uses a self-signed security certificate to encrypt communications. Over time, that certificate expires, just like a passport, blocking your devices from talking securely to the printer. I would request you to please follow the steps:

Renew the Certificate

1. Find Your Printer’s IP Address

• On the printer control panel:
• Go to Settings 
• click on Network 
• Select Wireless or Wired (depending on your connection), then note down the IP address.

2. Open the Printer’s Web Interface

• On your Mac:
• System Preferences 
• Printers & Scanners
• select your M252dw 
• Options & Supplies
• Show Printer Web Page.
• Or enter the IP in a browser’s address bar.

(macOS might display a “certificate not trusted” warning; just click “Advanced” → “Proceed” to move ahead.)
 

3. Generate a New Self-Signed Certificate

In the web interface:

• Go to Network → Advanced Settings → Certificates.
• Click Configure (next to “Printer Certificate”).
• Choose Create a New Self-Signed Certificate.
• Set the validity to the maximum (e.g., 3650 days or 10 years).
• Click Apply and wait a couple of minutes for it to finish.

4. Restart & Reconnect

• Restart your printer.
• On your Mac, resume the paused print job, and everything should flow smoothly now.
