Furthermore, the status is sent immediately after the request command has been received.
The data received cannot be guaranteed when Print data (ESC+"A" - ESC+"Z") is sent from the
host under the following conditions:
1) When the printer is OFFLINE
2) When an error occurs in the printer
Pin Assignments
Caution!
In the connections, it may be necessary to loop (usually kept "High) CS and RS on the host side
