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.
See the Appendix Auto Status for details regarding status.
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.
This command is not used when auto-status is valid.
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.
