• ENQ/ACK
In this protocol, the communication is controlled by the
control characters ENQ (ASCII 05 dec.) and ACK (ASCII 06
dec.) being transmitted on the same line as the data. The send-
ing unit transmits ENQ at regular intervals. If the response
ACK is not received, the transmission is held up awaiting
an ACK character from the receiving unit. By default, ENQ/
ACK is disabled.
• XON/XOFF
In this protocol, the communication is controlled by the
control characters XON (ASCII 17 dec.) and XOFF (ASCII
19 dec.) being transmitted on the same line as the data. XON/
XOFF can be enabled/disabled separately for data received
from the host by the printer (printer sends XON/XOFF) and
for data transmitted to the host from the printer (host sends
XON/XOFF).
XOFF is sent from the printer when its receive buffer is
fi lled to 75%, and the transmission from the host is held,
waiting for an XON character. When enough data have been
processed so the receive buffer is fi lled only to 50%, the printer
sends an XON character and the host resumes transmitting
data. The same principles apply to XON/XOFF sent by the
host, even if the percentage fi gure may differ.
By default, XON/XOFF is disabled for data both ways.

New Line

Selects the character(s) transmitted from the printer to specify the
switching to a new line. There are three options:
• CR/LF
• LF
• CR

Receive Buffer

The receive buffer stores the input data received on the serial
channel before processing. Default size is 300 bytes.

Transmit Buffer

The transmit buffer stores the output data to be transmitted on
the serial channel before transmission. Default size is 300 bytes.
ASCII 13 dec. + ASCII 10 dec. (default)
ASCII 10 dec.
ASCII 13 dec.
