Apropos. I just invented 3D-way to implement color laser printer. Firstly you have enclosed chamber with transparent top. Then you blow some color powder in the chamber. Maybe you apply some electrostatic forces to speed up the process. When the dust has finally settled on the paper, you just zap it with laser. The melted powder adheres to the paper at appropriate points. You suck the loose powder back to its container and repeat the process with next color. This is clearly more economical construction compared to Xerox-style laser printer. It collects the powder firstly on separate surface, heats that and then presses adhered shit to the paper.
