Interface Type

interface.
Data Protocol
You can select one of the following serial interface protocols to meet the host
interface requirements.
• XON / XOFF. 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.
