CHAPTER 5 CONTROL COMMANDS LIST ESC ACK SOH [Name] Inquire status [Format] ASCII ESC ACK SOH Hex 1B 06 01 Decimal 27 6 1 [Range] ------ [Default] ------ [Description] This command is effective only when using an interface capable of bi-directional data communications. When this command is received, the printer sends the status in real time to the host (not taking it from the reception buffer, but executing it immediately upon reception from the host). Bi-directional parallel interfaces enter a "data present" state. When in the serial interface DTR mode, and using a parallel interface, set so that the status can be inquired even when offline for errors, etc. When this command is sent once to the printer, do not send the next ESC ACK SOH command until the final auto status has been received.
