A YouTuber named smill simply completed a playthrough of Minecraft utilizing solely a receipt paper for visuals. He turned off his monitor, took screenshots of the sport one after the other and fed them straight into the printer. Every body got here out on a strip of thermal paper, a protracted blurry report of his journey. By the tip he had defeated the Ender Dragon, so you may end the sport this manner when you’ve got the endurance and a stack of paper rolls.
Thermal printers work by heating particular paper with tiny components within the print head. Darkish pixels get scorching spots that darken the floor, gentle areas keep white. No ink ever touches the paper. Smill connected a fundamental mannequin to his PC by way of USB and constructed a easy app to deal with the remaining. This system grabs a screenshot of Minecraft each second or so, resizes it to suit the slender paper and converts the colours to black and white patterns the printer understands.

Too many frames and the print head overheats from fixed heating, so velocity is vital right here. Smill settled on one body per second after experimenting and located that increased speeds precipitated jams or distorted output. Early runs used printed Twitch chat messages or digital camera views to calibrate the timing. For Minecraft this meant 0.5 to 1 FPS in apply, so gameplay was an anxious wait between updates.
Viewing these prints required some ingenuity, so Smill constructed a DIY respooler out of plastic blocks, chains and wheels. It wrapped the output paper again right into a loop so he might flip by the frames like a hand cranked flip e book. A number of rows of paper had been stacked throughout longer classes however jams occurred ceaselessly particularly throughout hectic moments. He navigated by staring on the blocky monochrome graphics, listening to the sport sounds (sheep bleats or enderman hisses) and counting on muscle reminiscence from earlier video games.
Minecraft is a sport that may work with a blocky look, however after some time, issues begin to go mistaken. Your stock slots merely fade into nothing on the interface, forcing you to click on blindly to create instruments or type issues out. Darkish sections, such because the Nether, will merely burn out your printer as a result of they’re so black, and then you definitely attain the Finish, the place every thing is simply this pristine sky and the dragon vanishes utterly. Smill was inventive sufficient to make use of hitboxes in debug mode to make the boss seem as a faint silhouette.
The coordinates on the F3 display had been practically ineffective for printing, subsequently he needed to depend on the help of different speedrunners to grasp the pathways for his seed. Paper was one other problem; it ran out rapidly, taking round 10 to fifteen minutes every roll, or 600 to 900 photographs. Smill had bought ten rolls however solely used 5 whereas making an attempt to resolve points together with his printer and software program. He had a run reduce quick within the Nether by a ghast fireball, and one other tousled on the Finish when he spent all of his beds on crystals. However he ultimately managed to place one thing along with a super-optimized world seed, quick portals, and a big quantity of stuff.
Smill’s printer app started so simple as you may suppose, with just one button to transmit something to the printer. However he quickly started so as to add automated timers and improved distinction to his hotbar. Not that anyone can see his code simply but, but when you recognize the basics of programming, you must be capable of recreate it utilizing sure printer management and display seize libraries. Merely join the {hardware}, feed screenshots by with a one-second delay, and watch the paper fly out.
It’s much like what Bringus Studios did with Doom: they despatched the sport frames to an Epson thermal printer and simply waited as much as 4 seconds each output to get the demon entrails on paper. It slowed motion considerably, however gamers had been nonetheless in a position to evade and take potshots by merely glancing on the rising strip. Each designs merely make use of the printer as one other show, permitting the PC to proceed operating the sport at full velocity within the background whereas the paper serves as the one window.
