Data Interfacing
Serial
The printer is shipped with the following serial settings as default: 115,200 baud, 8 data
bits, one stop bit, no parity, hardware flow control, and host transmission not blocked (this
last feature is intended for use with lower sophistication hosts that cannot read the
eXtendo® printer’s status data. It uses the hardware handshake lines to prevent the host
from sending more data if the printer registers “paper out”).
