7. Printer failure during order processing

If a printer fails while orders are being processed, the system will automatically alert the user.

The alert includes:

  • A sound notification

  • A system alert message

  • The Order ID associated with the failed print

This helps outlet staff quickly identify which order was affected and take corrective action.
