ESC ACK SOH
[Name] Inquire status
[Format] ASCII ESC
Hex 1B
Decimal 27
[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.
