So you've seen the video (previous entry), this is how it looks after printing.
It's a mock-up. The strip isn't long enough, I used whatever was left in the printer I bought to see how it will look like, so there are only 15 and a bit photos on it.
I did not edit the images at all. What you see is what you get. Raw footage of whatever was going on that person's mind, probably 10+ year old photographs (exciting!)
The paper is old, so the quality isn't the best. I need to test newer paper to see the difference in quality.
This is a proper gameboy printer paper, they come in slight color hues, this one being blue, others are yellow and red.
This printing process is very similar to till receipt paper, it's thermal and reacting to heat. Therefore with time, the images will fade.
A bit of information about the printer from the official Nintendo website:
The Game Boy Printer is a thermo-printer that prints photographs taken with the Game Boy Camera, or from games compatible with the Game Boy Printer.
A small chip in the printer is controlled by pulses that come from the camera/the game, thus creating various temperatures. These temperatures, in turn, shade the points heated on the special paper into various shades of grey, creating the image.
