Printer Port Connection
The Digital Counting Scale has a serial printer port that may be used to print weight and
associated data. The data is sent to the printer on demand when the PRINT key is pressed. The
printer connects to the counting scale via the 25-pin "D" connector (PRINTER) located on the
rear panel of the scale. Refer to Figure No. 4 for pin identification of the printer port connector.
NOTE: The serial printer port has a fixed data format, configured for 9600 baud, 8 data bits, No
parity and 1 stop bit (9600,8,N,1) operation.
