No he clearly says no ink and no toner. Toner is melted onto the paper after a laser (now mostly LEDs) heat up a drum. He’s talking about burning the paper with a laser… Which would be interesting but really hard to do where a top layer is burned black without toasting the rest of the layers.
I get the sense that everyone responding to this is completely missing the joke.
They mean laser printers, people.
Laser printers don’t burn the paper. They require toners. So it wasn’t a joke unless they also didn’t know how a laser printer works.

Pretty sure that’s how my receipt printer works, but it’s just one color onto specialized paper.
