The Game Boy Printer is a thermal printer accessory released by Nintendo in 1998, which ceased being manufactured in early 2003. The Game Boy Printer is compatible with all the Game Boy systems except the Game Boy Micro, and is designed to be used in conjunction with the Game Boy Camera & link cable. It also prints images from compatible late-generation Game Boy and Game Boy Color games.
Basically you can take pictures with a vintage gameboy and print them!
