Dear Ahmed,

The error message you're getting with your Epson TM-T83III printer indicates a potential issue with the communication between your browser and the printer due to a security certificate. Here's a breakdown of the message and some solutions:

The Problem:

• Your browser might be blocking the connection to the printer due to a self-signed certificate. Self-signed certificates are not recognized by most browsers as trusted, raising security concerns.

Possible Solutions:

1. Check Printer Connection:
   • Double-check that your printer is physically connected and powered on.
   • Verify your computer recognizes the printer and it's set as the default printer.
2. Accepting the Self-Signed Certificate (if applicable):
   • The message mentions "https://192.168.1.55". This could be the IP address of your printer.
   • If you're comfortable with potential security risks, you can try accessing this address in your browser. This might prompt you to accept the self-signed certificate. Warning: Only do this on a trusted network and if you understand the security implications.
3. Odoo Documentation:
   • The message suggests referring to Odoo's documentation for two solutions:
     • "Self-signed certificate for ePOS printers": This section likely explains how to configure Odoo (if that's the software you're using) to accept the self-signed certificate from your printer.
     • "Secure connection (HTTPS)": This section might guide you on setting up a secure connection (HTTPS) between your browser and the printer, eliminating the need for a self-signed certificate.

Additional Tips:

• Consult your printer's manual or Epson's support website for specific instructions on certificate management for the TM-T83III model.
• If you're unsure about certificate management or Odoo configuration, consider seeking help from a network administrator or IT professional.

By trying these solutions, you should be able to resolve the certificate issue and print your receipts successfully. Remember to prioritize security and only accept self-signed certificates on trusted networks.
