I did this for a single color from a single printer—the black toner from my Brother laser printer. I left it in my West facing office window for about 18 months. On the BACK SIDE I labeled it with pen. The pen on the back faded to almost nothing but the toner did not fade at all.
I did not do monthly scans, that would have been a better "experiment", but I was satisfied that a B&W laser print would last a very long time.
Maybe I should lightfast test my Brother Laser and my HP Inkjet (with Black Pigment based ink).
I thought that pigment based inks would be both waterproof and lightfast. Since I started to airbrush watercolor over my HP prints I am now very aware that these pigment based inks are not waterproof, even after long drying times.

Crazy amount of effort here. Awesome.
