I'm a huge fan of this. There's something magical about receipt printers. I love the idea that there is a long, infinite canvas which can flow from the printer. And part of the allure is the clunky slowness of the printer and the rough analog quality of the print. That rendering of the mountains works very well for the medium!

Sorry for the self promo, this is just too relevant not to share: I created a generative art piece using receipt printers in which the printers "print themselves to death" over a tub of water. Video here: https://vimeo.com/336939272
