Thermal Receipt Print
A strip of thermal paper feeds up out of a printer slot, each dot row printing as it passes the head, then tears off when the receipt is done. Tokens feed the paper, so fast streams race it out.
Also known as: receipt printer shader, thermal printer animation, dot matrix receipt glsl, printing receipt effect.
