Resetting the Default Serial Port Parameters
Do the following to reset the communications parameters on the printer to the factory defaults
(serial communication settings are: 9600 baud, 8 bit word length, NO parity, 1 stop bit, and
DTR/XON/XOFF data flow control).
1. Press and hold the feed button until the green status LED flashes once, pauses, flashes
twice, and pauses and flashes three times. Release immediately.
