@NobleONe From what I’ve read, you need to remove the RFID chip from a roll and use custom firmware. I need to double-check the steps, but apparently you place the chip near the bottom of the Niimbot, start printing, and then move it out of the way. My understanding is that if you turn the printer off or bring the chip back near it, it’ll count all the prints made while the chip was out of the way.
I did see the black and red ribbon, but from the examples on the Niimbot website, I thought you could only print black on the left side and red on the right.
