[Notes]

  • The printer processes each Real-time commands that is enabled (b = 1, 49) upon receiving it.
  • A Real-time commands specified as disabled (b = 0, 48) is not processed.
  • Setting of this command is effective until ESC @ is executed, the printer is reset, or the power is turned off.
  • If you transmit a command for graphics data or definition data that contains the sequence DLE DC4, be sure to disable real-time command (b = 0, 48) processing before transmitting the graphics data or defined data command. Then the printer will process the sequence DLE DC4 as image data.
  • If graphics data includes a data string matching DLE DC4 (fn = 1 or 2), it is recommended to use this command in advance to disable the Real-time commands.
