Game Boy Printer
The Game Boy Printer, known in Japan as the Pocket Printer (ポケットプリンタ Poketto Purintā ), is a thermal printer accessory released by Nintendo in 1998, while it ceased manufacture 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. It also prints images from compatible late-generation Game Boy and Game Boy Color games (listed below). It runs on six AA batteries and uses a special 3.8 cm wide thermal paper with adhesive backing, sold in white, red, yellow and blue colors. In Japan, a bright yellow Pokémon version of the Game Boy Printer was released, featuring a feed button in the style of a Poké Ball.
Mad Catz sells a kit that enables users to connect a Game Boy to a PC and print images using the PC's printer. Hobbyists outside the UK can also make their own cable for uploading images to their computer. A Game Boy Printer emulator is needed for the Game Boy to interface with the PC once linked via cable. The Game Boy Printer Paper has also been discontinued, and rolls of the genuine article which still produce a reliable image are getting harder to find. Regular thermal paper, such as the kind used for POS terminals can be cut to the proper width and used successfully with the Game Boy Printer.
The system will print a test message reading "Hello!" if it is turned on while the feed button is held. According to the manual, this is used to test if the printer is functioning properly. To get around using six AA batteries for the printer, a single 9V battery can be used if wired properly, since the printer runs on 9 volts DC.

Game Boy Printer paper 
A roll of the American Game Boy Printer paper came in red, blue, yellow and white, and had a width of 3.8 cm. A typical roll had 390–400 cm of length. When a picture printed from the Game Boy Camera, it would print with a .5 cm margin above and below the picture and print the picture at a 2.3 cm height. This would give the total of 3.3 cm height per picture. The Game Boy Printer paper refills boasted up to 180 pictures per roll. With the math the typical roll could only take 118 pictures. The paper is now hard to find; it could be substituted with a 1.5-inch-wide (38 mm) thermal paper without repercussions on the printer.
Pokémon Pinball has a glitch to where it will only print the RED high scores.
