•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 may need to
use RS-422 to prevent data loss. You also may need to increase the
Buffer Size in K parameter from the default (1 Kbyte) to improve
performance.
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.
Stop Bits
Sets the number of stop bits in the serial data word. Either one or two stop bits
can be selected. The setting must match the corresponding stop bit setting in
the host computer.
Parity
Set for odd parity, even parity, mark, sense, or no parity. The setting must
match the corresponding parity setting in the host computer.
