Just for the translation:
Jan is talking about what is called "Schwellpapier" in German.

Here is a fuser device to emboss the areas that are black:

The touble with this is, what you already mentioned:
It's only black and white.
My test on greyscales was clear, you can definitely not distinguish between grey and black.

This limits objects, icons and textures to only two levels.

Best regards
