From Zelda Wiki.org
The Game Boy Printer (ポケットプリンタ Pocket Printer) was an accessory for the Nintendo Game Boy. It is a thermal printer that connects to the Game Boy with a Game Link Cable. It was released at the same time as the Game Boy Camera. It takes 6 "AA" batteries and is compatible with all models of the Game Boy (except for the Game Boy micro).
In The Legend of Zelda: Link's Awakening, it could be used to print photos from the Photographer in Tal Tal Heights. It was also compatible with a few dozen other games, notably including several Pokémon games.
