HOST INTERFACE
The response characters are described in Table 2.
•
SERIES1 2 CHAR. This protocol behaves exactly the same as the
Series1 Char except there is a two-character response to the host. The
response characters are described in Table 3.
•
DTR. The printer controls the data flow by sending 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.) DTR is not available when RS-422
is selected.
Baud Rate
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.
The choices for the RS-232 and RS-422 interfaces are 600, 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115200 Baud. The default is 9600
Baud.
NOTE: If you select a baud rate that is greater than 19200, you may need to

use RS-422 or select a lower baud rate to prevent data loss. You also
may need to increase the Buffer Size in K parameter to improve
performance.
