The latest update to the printing press: adding a 3d printer to print new plates, and a recycler to reuse that plastic once you've printed your page.

Uses 10x the energy, recycled plastic gets junked because of ink contamination, but still 25% cheaper than running an hp inkjet because you can use bulk ink and don't have to keep replacing your dried up CMY inks to stop it from refusing to print your black and white document.
