[Notes]
• When the DTR/DSR control is selected, the printer only
transmits 1 byte (Printer identification) after it has been given
confirmation that the host is ready to receive data. If the host
is not ready, the printer waits until it is.
• When the XON/XOFF control is selected, the printer only
transmits 1 byte (Printer identification) if it has not been given
confirmation that the host is ready to receive data.
• This command is carried out once the data has been
processed in the reception buffer. There may therefore be a
delay between the moment in which the command is
received and that in which the data is transmitted, depending
on the status of the reception buffer.
• The types of status transmitted can be seen below:
