Hello,
I would like to know if there is a way to listen on Arduino when the printer button is pressed.
The default event is to push slightly the paper, but I would be interested if it produces some signal to one of the RX/TX pins from the board.
I am referring to the button that is just above the green led:

Thank you!

Re: Mini Thermal Printer button custom event
The printer user manual says nothing about anything like that coming back on the serial line. You could always try it emprically, and see if anything is transmitted.
Have a look at the parallel (LPT) interface on page 6 of the user manual. One of those like may be your button, in which case you could probably bring the signal back as a digital input to your Arduino. You'll have to see what the voltage of the signal is, and make sure it's within the 5V limit of Arduino GPIO inputs.
