I have an Epson SC P400. I am considering using your solution to make it chipless. In the instructions for the P400, you say
"If Your printer CAN ACCEPT downloaded Firmware and switches OFF after pressing STOP button - that means Your printer can be updated to Chipless Firmware!"
The P400 does not have a STOP button. It has these six buttons: POWER, WIFI, NETWORK STATUS, PAPER/CANCEL, INK, ROLL PAPER.
Which button is it?
