  • ESC/POS Handshaking Protocol is not required for this function.

[Notes]

  • This function works both in user setting mode and during normal printer operation.
  • This function transmits "Header to NUL" as follows:
  • Send data

  • (∗1)
    Communication condition transmits the value of a is converted into character data expressed by decimal numbers.
    Example:
    When [Communication condition] is the baud rate (a = 1), it is 1-byte data of "1" [Hex = 31h / Decimal = 49].
    (∗2)
    "Setting value" is set by GS ( E   <Function 11> . It might differ from the current communication condition before executing GS ( E   <Function 2> or depending on the setting of the DIP switch.
    Example:
    When the baud rate is 9600 bps, it is 4-byte data of "9600" [Hex = 39h, 36h, 30h, 30h / Decimal = 57, 54, 48, 48].
  • This function is used to confirm whether GS ( E   <Function 11> ends normally before executing GS ( E   <Function 2> .
  • See [Notes for transmission process] for process sending data group.
