GameBoy Printer emulator

[numuuu]

pretty self-explanatory, there already is quite a few arduino gameboy printers emulators for printing images (mostly GameBoy Camera stuff) straight from your gameboy,

A big advantage here, besides the neat all-in-one aspect, would be the integrated screen which could (maybe? dont know how hard that would be to implement) be used for image preview and the integrated SD card to write files to (most GBP emulators AFAIK use either serial transfer to a PC via a special program or wifi tranfer)

Hardware wise its just a matter of a few wires link cable so it could be integrated as a custom adapter and/or as a specific header in a future hardware revision just like the N64 controller plug
