• When DTR/DSR control is selected, the printer transmits only 1
byte after confirming the host is ready to receive data (DSR signal
is SPACE). If the host computer is not ready to receive data (DSR
signal is MARK), the printer waits until the host is ready. When
XON/XOFF control is selected, the printer transmits only 1 byte
without confirming the condition of the DSR signal.
• This command is executed when the data in the receive buffer is
developed. Therefore, there may be a time lag between receiving
this command and transmitting the status, depending on the
receive buffer status.
