Supplementary explanation

  • This API can be used in an environment that can be connected to both the Internet and the printer.
  • This API cannot be used simultaneously with other APIs.
    After executing this API, do not execute any other API until the callback is returned.
  • Do not turn off the power supply to the printer while executing this API.
  • This API can be used in the system configuration of the TM printer model and customer display model.
    With the system configuration of the TM Printer + DM-D + barcode scanner model, this API can be used when connecting via Bluetooth or USB.
  • This API cannot be used with SSL/TLS communication.
  • Since it takes time to send and receive large amounts of data over BLE connection, this API cannot be used with BLE connection.
