The '''Game Boy Printer''', known as the {{nihongo foot|'''Pocket Printer'''|ポケットプリンタ|Poketto Purinta|lead=yes|group=lower-alpha}} in Japan, is a [[thermal printer]] accessory released by [[Nintendo]] in 1998 which ceased production 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 battery|AA batteries]] and uses a proprietary 38mm wide [[thermal paper]] with adhesive backing, originally 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.

Released alongside the Game Boy Printer in 1998, Nintendo-manufactured thermal paper refill rolls were produced in white, cream, blue, yellow, and red variants, all of which had an integrated adhesive backing. 

After powering the printer on, a clip at the rear of the protruding translucent grey refill housing is depressed, allowing this to be lifted away. The thermal paper roll inserted upside-down and unravelled end facing down, with this end being fed into a thin slot. The maroon 'FEED' button is then pressed down, which engages the uptake motor, and pulls the paper through to the exit slot which has an integrated serrated edge, which allows finished prints to be ripped away from the roll. Forcibly pulling the paper opposite to the feed direction causes permanent damage to the gearing within the feed mechanism.

When a picture was printed from the Game Boy Camera, it would print with a {{cvt|5|mm}} margin above and below the picture and print the picture at a {{cvt|23|mm}} height. This would give the total of {{cvt|33|mm}} height per picture. Although on-box advertisements boasted up to 180 pictures per roll, in actuality a typical roll could only print between 118 and 121 pictures.

Sold on the official Nintendo e-Shop (as triple packs of blue, cream and white rolls) until 2007, Game Boy branded official replacement thermal paper is now difficult to source. Even brand-new, sealed, un-opened official rolls degrade relatively quickly once opened (if they were stored correctly and their seal has not failed). Most, however, have suffered degradation whilst in storage due to a chemical reaction between the thermal paper and adhesive backing layer.<ref>{{Citation|last=Flickr|title=game boy printer problems|date=10 June 2006|url=https://www.flickr.com/groups/gameboycamera/discuss/72157594161638731/|access-date=2020-09-17|archive-date=2017-01-20|archive-url=https://web.archive.org/web/20170120223256/https://www.flickr.com/groups/gameboycamera/discuss/72157594161638731/|url-status=live}}</ref> Due to the proprietary nature of the adhesive-backing, replacement thermal paper that is able to be adhered to surfaces once printed upon (including brands such as 'MAXStick') is prohibitively expensive.

Instead, the thermal paper rolls can be successfully substituted with a '''38mm x 4m''' alternative, with or without ('core-less') spindle cores, without repercussions on the printer. Such rolls are also compatible with some hand-held printing calculators, such as the Canon TP-8, Texas Instruments 5000–2008, Sharp 8180, and Casio FX-802. Alternatively, wider rolls (such as '''57mm x 30mm x 12.7mm''') can be cut or trimmed to 38mm, and function without issue.

Please note, however, that due to the inherent limitations of thermal paper, photographs printed on thermal paper will fade over time (this depends heavily on the thermal paper variant used, and could be as short as a few months, or instead a few years) until the paper is virtually blank. Paper in this state can usually be re-used, as long as the length of the strip is long enough to be manually fed into the takeup.

It is unknown whether original Game Boy Printer paper contains the chemicals [[Bisphenol A|Bisphenol-A]] (BPA) or its analog [[Bisphenol S|Bisphenol-S]] (BPS). Previously very widely used in plastics and thermal receipt paper due to their heat resistance and stability, these are currently being phased out of thermal paper coatings due to their in-vivo accrual (via direct dermal absorption) and resultant oestrogen-mimicking and endocrine disruption.<ref>{{Cite web |last=Bienkowski |first=Brian |date=2013-01-17 |title=BPA Replacement Also Alters Hormones |url=https://www.scientificamerican.com/article/bpa-replacement-also-alters-hormones/ |access-date=2020-09-17 |website=Scientific American |language=en |archive-date=2021-06-18 |archive-url=https://web.archive.org/web/20210618110315/https://www.scientificamerican.com/article/bpa-replacement-also-alters-hormones/ |url-status=live }}</ref> Modern thermal paper roll replacements, or their manufacturers, usually clearly state if they are Bisphenol free [BP-Free].

==Protocol==

The communication between the Game Boy and the Game Boy Printer is via a simple serial link. Serial clock (provided by the Game Boy for the printer), serial data output (from Game Boy to printer) as well as serial data input (to Game Boy from printer). The Game Boy sends a packet to the printer, to which the printer responds with an acknowledgement as well as a status code.<ref>{{cite web|url=http://gbdev.gg8.se/wiki/articles/Gameboy_Printer|title=Gameboy Printer|website=GbdevWiki|access-date=2017-04-09|archive-date=2021-06-03|archive-url=https://web.archive.org/web/20210603211734/https://gbdev.gg8.se/wiki/articles/Gameboy_Printer|url-status=live}}</ref><ref>{{cite web|url=https://www.mikrocontroller.net/attachment/34801/gb-printer.txt|title=GB Printer interface specification|date=December 1, 2001|archive-url=https://web.archive.org/web/20090615192718/https://www.mikrocontroller.net/attachment/34801/gb-printer.txt|archive-date=June 15, 2009|url-status=live}}</ref><ref name=":0">{{cite web|url=https://shonumi.github.io/articles/art2.html|title=In Depth: The Game Boy Printer|date=September 7, 2016|website=Shonumi|access-date=April 11, 2017|archive-date=June 3, 2021|archive-url=https://web.archive.org/web/20210603211621/https://shonumi.github.io/articles/art2.html|url-status=live}}</ref>

=== Packet Format ===
Communication is via the Game Boy sending to the printer a simple packet structure as shown below. In general, between the first "sync_word" til the checksum is the Game Boy communicating to the printer. The last two bytes of the packet are for the printer to acknowledge and show its current status code.

* Command may be either Initialize (0x01), Data (0x04), Print (0x02), or Inquiry (0x0F).
* Payload byte count size depends on the value of the `DATA_LENGTH` field.
* Compression field is a compression indicator. No compression = 0x00
* Checksum is a simple sum of bytes in command, data length, and the data payload.
* Status byte is a bit-field byte indicating various status of the printer itself. (e.g. If it is still printing)

=== Commands ===

==== Initialize (0x01) ====
* Typical Payload Size = 0
This packet is sent without a data payload. It signals to the printer to clear the settings and prepare for the first data payload.

==== Data (0x04) ====
* Typical Payload Size = 640
The data packet is for transferring the image data to the printer data buffer. The typical size of the data payload is 640 bytes since it can store two printable rows of 20 standard Game Boy tile (2 bit color in 8x8 pixels grid), of which the Game Boy tile takes 16 bytes.<ref>{{Cite web|url=http://www.huderlem.com/demos/gameboy2bpp.html|title=Gameboy 2BPP Graphics Format|last=Huderle|first=Marcus|date=June 29, 2013|archive-url=https://web.archive.org/web/20180625064314/http://www.huderlem.com/demos/gameboy2bpp.html|archive-date=June 25, 2018|url-status=live|access-date=April 11, 2017}}</ref>

==== Print (0x02) ====
* Typical Payload Size = 4
This commands the printer to start printing. It also has 4 settings bytes for printing.<ref name=":0" />

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 (1.5 volts each) for the printer, a single [[Nine-volt battery|9V battery]] can be used if wired properly, because the printer requires 9V DC.{{Citation needed|date=February 2019}}
