Interface Type
This parameter configures the electrical interface for the serial port, as follows:
v RS-232 (the default)
v RS-422
Data Protocol
You can select one of the following serial interface protocols to meet the host
interface requirements.
v XON / XOFF (the default). Transmit On / Transmit Off. The printer controls the
v ETX / ACK. End of Text / Acknowledge. The host controls the flow of
v ACK / NAK. ACK means acknowledge; the device acknowledges it has accepted
v DTR (DTE Ready). The printer controls the data flow by asserting or deasserting
Baud Rate
This parameter sets the baud rate of the serial interface in the printer. Baud rate is
the speed at which serial data is transferred between the host computer and the
printer.
v 9600 Baud (the default)
v 19200 Baud
v 38400 Baud
v 57600 Baud
v 115200 Baud
v 600 Baud
v 1200 Baud
v 2400 Baud
v 4800 Baud
Data Bits
The DATA BITS parameter sets the length of the serial data word. The length of
the data word must match the corresponding data bits setting in the host
computer.
v 8 (the default)
v 7
Stop Bits
The STOP BITS parameter sets the number of stop bits in the serial data word. The
setting must match the corresponding stop bit setting in the host computer.

communication to the printer by sending a block of data and ending the block
with an End of Text (ETX) signal. When the printer receives the ETX signal, it
will acknowledge the ETX, thereby acknowledging it has received the entire
block of data.

this hardware signal to the host. If there is enough room in the printer buffer,
the printer will send a high signal; if the buffer is full the printer will send a low
signal. DTR tells the host if it is safe to send more data. (If the host sends data
during an unsafe condition, data will be lost.)
