*Make sure that command is issued before transmission of print data. (commands are stored in the input buffer and executed sequentially)
*Reception is available except in the buffer full status.
*The commands above are valid only for serial interface.
*Regarding DTR/DSR control, only one byte is transmitted after confirmation that the host is able to receive data, that is DSR signal is in SPACE status. For XON/OFF
control, one byte is transmitted without confirmation of DSR signal status.
*For DTR/DSR control, if host is not in a receivable status, it waits until host can receive data.
