While monitoring printer status, do not use this function to send the ASB status transmit disable command (GS a), or it will
make it impossible to acquire status.
The BiDirectIOEx ASB (Auto Status Back) suppress specification is specified so that a response other than the
expected response (such as Status) will not be received if a command is sent for which a response is expected from
the printer. If ASB is not suppressed, it is necessary during programming to give consideration to the reception of
data other than the expected data.
Specifying the receiving buffer or not specifying it is equivalent to specifying processing of data received from the
printer by BiDirectIOEx or specifying processing by the monitoring thread (notification by callback or BiGetStatus).
