This. Based on my (elementary) understanding of laser printers, you have to have a laser zap a transfer belt to charge it so that it will elecromagnetically attract the toner, then precisely lay down a fine layer of toner onto the belt, then lay the microplastics + iron filings from the belt onto the page, repeat this four times, then roll the page through a tiny oven to bake on the thin, shiny layer of plastic. It's very complicated, and have you seen the price of new fuser units or transfer belts?
