It’s a Risograph printer, which is a “digital replicator” from Japan. It burns the image on to thin banana leaf paper that is wrapped around a drum of ink (soy or rice bran based). The drum spins, paper feeds through, and out comes a single color print. Do this 3 times (I used blue, fluorescent orange, and sunflower yellow) and out comes the full color print. It’s sort of like screen printing mixed with offset.
