@Serjios, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding an error message! 

We're thrilled to have the opportunity to assist you and provide a solution.  

I see you’re facing a "Cannot Print – Expired Certificate" error on your HP Color LaserJet Pro MFP M277dw. No worries, I’ll help you get this sorted!

This issue usually happens due to an expired self-signed certificate used for secure communication. Here are some steps to resolve it:

Try This First:

Restart the Printer & Network

• Turn off the printer and unplug it.
• Restart your router.
• Wait for 30 seconds, then power the printer back on.

Update Printer Firmware

• Go to HP Support → HP Software & Driver Downloads
• Enter your printer model and download the latest firmware update.
• Install it on the printer and restart it.

Regenerate the Certificate (If Using Secure Print Features)

• Open a web browser and type your printer’s IP address (Find it in the printer’s network settings).
• Navigate to Networking → Security → Certificates.
• Delete the expired certificate and create a new self-signed certificate.

Check Printing Settings

• On your computer, go to Control Panel → Devices and Printers.
• Right-click your HP printer and select Printer Properties.
• Under the Ports tab, ensure you’re not using a secure HTTPS port unless necessary.

A Few Quick Questions to Narrow It Down:

❓ Are you trying to print over a network (Wi-Fi) or USB?
❓ Have you recently updated your computer or printer firmware?
❓ Are you using any third-party security software or firewall that might be blocking secure communication?

Try the steps above and let me know how it goes! If the issue persists, we can dig deeper. 😊  

Take care, and have an amazing day!
