3.3 XON/XOFF
This communication protocol tells the printer status if it can receive any data or not to the host by sending "XON" (HEX 11H) or
"XOFF" (HEX 13H) to the signal line. Single item receive or multiple receive can be switched on the interface mode of the
printer.
When the print data (STX <A>~ <Z> ETX) has sent from the host in the conditions below, the received data will not be accurate.
1) When the printer is in offline state.
2) When an error has occurred in the printer.

*Depending on the model of the host, CS and RS may need to be looped (always keep "High") at the host.
Please confirm the user's guide of the host system.
