Robust Xon/Xoff--this data stream handshake
is an extension of the Xon/Xoff data stream
handshake.  If no data is received within
one second of the transmission of an Xon, it
sends additional Xon characters at one
second intervals.

F

Data Terminal Ready (DTR)--the DTR line
indicates whether or not the printer can
receive data (READY) or not (BUSY).  When
the printer is READY, the DTR signal
switches to a HIGH state (unless the DTR
line has been set to inverted operation, in
which it switches to a low state) as a
request for data.

The printer requests data when the print
buffer is near empty.

The printer switches DTR to BUSY when the
print buffer is near full.  When the printer
is turned on, the DTR signal is held at BUSY
until the printer has completed SELF TEST
and WARM UP.

Baud Rate (Serial) The Baud Rate is the rate at
which the information is sent from the host
computer to the printer.  Baud rate is measured
in bits per second (bps).  The factory default
setting is *

 and this setting is normally

appropriate, but the setting must correspond to
the baud rate setting at the host computer.

The following baud rates are supported:  300,
600, 1200, 2400, 4800, 9600, 19200, and 38400.
