An FFGL effect that prints your clip on a thermal receipt printer: a line of tiny heaters, 8 to the millimetre, and no ink, just paper that darkens where it gets hot enough. It prints one dot row at a time, and the look comes from the heat rather than being drawn. Tone is a Bayer, Floyd-Steinberg or Atkinson dither. A heater that fired is still warm on the next row, so lines thicken, marks run on below themselves and dark areas block up unless the firmware's history control takes the heat off. The supply can only fire so many dots at once, so dense rows print paler and band at the strobe blocks. A slipping roller repeats or overprints rows, and in Printing mode the receipt scrolls out of the slot and tears off.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
