The NeoGB Printer - ポケットプリンタエミュレータ
The NeoGB Printer is a SD card-based standalone Game Boy Printer emulator. It is easy to build with parts readily available on the market. It does require little to no soldering skill and is fast to install from Arduino IDE (few dependancies). Using it is straigthforward and intuitive. Mounting the device with all parts on a table requires about an afternoon from opening the component bags to printing.
This project is very similar to a popular ready-to-use solution available on the market, but the NeoGB Printer is open-source, cheap and tested with success with all officially released games (110 in total) that support the original Gameboy Printer. The total cost for all the parts bougth new is below $15. All parts can be easily exchanged with other projects, reused or harvested from dead electronics as they are all very common.
You just need to upload the code using the Arduino IDE, connect the components like described here, plug your SD card and print any image directly from a Gameboy compatible game. Serial protocol is directly recorded under binary form on SD card. Once your printing session is finished, hold the button for a few seconds and all the recorded data will be quickly converted to BMP and/or PNG images, ready to use with social media. Reboot the device once and you will access to an intuitive webserver mode.
