Data Protocol
You can select one of the following serial interface protocols to meet the host interface requirements.
•
XON / XOFF (factory default). The printer controls the flow of communication from the host by turning
the transmission on and off. In some situations, such as when the buffer is full or the timing of signals
is too slow or too fast, the printer will tell the host to stop transmission by sending an XOFF character.
An XOFF character is sent when the number of empty bytes in the buffer is less than or equal to 25
percent of the buffer size. If the host keeps sending data after an XOFF is sent, the printer firmware
will continue to send an XOFF for every 16 characters received. When cleared, the printer will resume
receiving data (XON). The data does not have any End of Text codes; XON / XOFF is a non- block
protocol.
•
ETX / ACK. End of Text / Acknowledge. The host controls the flow of communication to the printer by
sending a block of data and ending the block with an End of Text (ETX) signal. When the printer
