HOST INTERFACE
•
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.
NOTE: If you select a baud rate that is greater than 19200, you

Word Length

Sets the length of the serial data word. The length of the data word
can be set to 7 or 8 bits, and must match the corresponding data
bits setting in the host computer.

may need to increase the Buffer Size in K parameter from
the default (1 Kbyte) to improve performance.
