No need to power-cycle the counter. Just enable "Printing" using the "Save & 
Print" button: Press the button until you see "PRINT: OFF" then use the cursor 
keys right side of the display to switch to "PRINT: ON", then hit the "ENTER" 
button. The counter will start printing on the serial port.

Default serial settings: 9600 baud, 8N1.
