If I don't use them at all will it affect the printing function? And If I just use the serial communication as shown in the bildr tutorial for printing will it work with this printer? I kindly request you to re-frame a conclusive wiring for the Arduino and my Thermal printer from studying briefly the data-sheet (the data sheets attached).
I Think powering it , then connecting the Rx-TX and TX-Rx and GND will do enough as given in bildr tutorial.
Thank you
