If you’re experiencing issues with your HP LaserJet Pro MFP M126nw printer not printing through an OpenVPN connection, despite other printers working fine, you’re not alone. This problem often arises due to specific network configuration issues. In this guide, we’ll walk you through some troubleshooting steps to resolve this issue.
Check Printer IP Configuration
First, ensure that the IP address of your HP LaserJet Pro MFP M126nw printer (192.168.2.64) is correctly configured. This printer should be set with a static IP to avoid any IP conflicts.
- Access Printer Settings: Navigate to the printer’s web interface using a browser and the printer’s IP address.
- Verify IP Address: Ensure the IP address is correctly set to 192.168.2.64 and is not conflicting with other devices on the network.
Verify VPN Configuration
Confirm that your OpenVPN configuration is set up to route traffic properly.
- Check Routing Tables: Ensure that your OpenVPN server and client configurations include routes to the printer’s IP range (192.168.2.0/24). This is crucial for directing print jobs through the VPN.
- Example routing command in OpenVPN server configuration: code
route 192.168.2.0 255.255.255.0 - Update VPN Configuration: Ensure that your VPN client configuration file includes the correct routes and settings to access the printer network.
Firewall and Security Settings
Firewall rules on either the OpenVPN server or the client machine could be blocking the print traffic.
- Check Firewall Rules: Verify that the firewall on the OpenVPN server and client allows traffic on the printer’s port (typically TCP port 9100 for HP printers).
- Add Exceptions: Add exceptions in the firewall settings to allow communication with the printer’s IP address.
Printer Driver and Compatibility
Ensure that the printer drivers installed on the client machine are up-to-date and compatible with the printer model.
- Update Drivers: Download and install the latest drivers from HP’s official website for the HP LaserJet Pro MFP M126nw.
- Reinstall Printer: Remove and reinstall the printer on your client machine to ensure correct driver installation and configuration.
Test Connectivity
Test the connection to the printer from the remote VPN client to confirm if it’s a specific issue with the printer or the network.
- Ping the Printer: Use the ping command from the VPN client to ensure connectivity to 192.168.2.64.
- Try Printing a Test Page: Send a test print job to the printer to see if it goes through. If the printer is reachable but not printing, the issue may be with the print job configuration.
Check Printer Settings
Verify the printer’s network settings to ensure it’s set up correctly to receive print jobs over the network.
- Network Configuration: Access the printer’s network settings via its web interface and make sure it’s configured correctly.
- Print Queue: Check if there are any stuck print jobs in the queue that might be blocking new print jobs.
Consult Documentation and Support
If you’ve tried the above steps and the issue persists, consult the documentation for both your OpenVPN setup and the HP printer. There may be specific settings or firmware updates that address compatibility issues.
- OpenVPN Documentation: Review the OpenVPN documentation for advanced network routing and configuration tips.
- HP Support: Reach out to HP’s support for assistance with specific printer issues.
Conclusion
By following these troubleshooting steps, you should be able to resolve the issue of your HP LaserJet Pro MFP M126nw printer not printing through an OpenVPN connection. Ensure that all configurations are correctly set up and that both network and printer settings are optimized for VPN usage. If you continue to face issues, seeking help from technical support may be necessary.
