Hi @DanielOr,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

An expired certificate error when using your HP Color LaserJet Pro M252dw printer with a MacBook Pro can arise due to several factors related to security settings or outdated software. Here's how you can address and potentially fix this issue:
 

Steps to Fix Expired Certificate Error

1. Update Printer Firmware:
   • Ensure that the printer's firmware is up to date. An expired certificate may be resolved by updating to the latest firmware version.
   • Visit the HP Color LaserJet Pro M252dw Software and Driver Downloads | HP® Support, download any available firmware updates.
      
2. Update macOS:
   • Make sure your MacBook Pro is running the latest version of macOS. Go to System Preferences > Software Update to check for updates.
      
3. Update Printer Driver:
   • Sometimes the drivers might be outdated, causing communication issues. Update to the latest printer driver:
     • Go to System Preferences > Printers & Scanners.
     • Remove the existing printer by selecting it and clicking the minus (-) button.
     • Re-add the printer by clicking the plus (+) button, and select your printer from the list.
     • Ensure that the latest drivers are automatically selected during this process.
        
4. Reset Printing System:
   • Sometimes resetting the printing system on your Mac might resolve certificate errors:
     • Go to System Preferences > Printers & Scanners.
     • Right-click or control-click in the Printers list and choose "Reset printing system."
     • This will remove all printers and their settings. You will need to re-add your printer afterwards.
        
5. Clear Browser Cache (if using Web Interface):
   • If you access the printer's web interface, clear your browser's cache and cookies to remove any old security certificates that might be causing the issue.
      
6. Check Date and Time Settings:
   • Verify that the date and time are correctly set on both your MacBook Pro and the printer, as discrepancies can cause certificate errors.
      
7. Disable Certificate Checking (Not Recommended):
   • Temporarily disable certificate validation in your print setup to determine if this is causing the issue. However, this is not recommended for long-term use as it can pose security risks.

I hope this helps.

Take care and have an amazing day!
