The parameter a is needed only when n = 7, 8 or 18. DLE EOT BEL is DLE EOT (n = 7); for some previous printer models this command is called DLE EOT BEL.

[Notes]

  • This is a Real-time command. Refer to Notes of Real-time Commands for usage note.
  • When this command is transmitted, do not transmit data that follows until the corresponding status is received.
  • However, if this command must be transmitted continuously, it is possible to transmit up to 4 commands at once.
  • In this case, do not transmit data that follows until the all status is received.
  • Be aware that if you designate continuous transmission in excess of the limit, the status may not be transmitted.
  • Each status consists of 1 byte, and the value is 0xx1xx10b.
  • The real time status can be differentiated by the bits 0, 1, 4, and 7 from other transmission data, except for data in block data (Header – NUL).

    Drawer kick-out connector pin 3 (bit 2) indicates the buzzer sounding status when the optional external buzzer is connected. It will be HIGH while sounding and LOW otherwise.
    Online recovery wait (bit 5) is changed when GS ^ is executed or the printer is waiting for the paper feed button to be pressed for removing a label or for roll paper to be replaced for some models.

    • If recoverable error (bit 2) or autocutter error (bit 3) occurs due to paper jams or the like, it is possible to recover by correcting the cause of the error and executing DLE ENQ (n = 2).
    • If an unrecoverable error (bit 5) occurs, turn off the power as soon as possible.
    • The cause of the error can be checked by the offline response (when an offline cause is added). See Function 49 of GS ( H.
