With all the interest in 3D printer and large communities building their own printers, where are the amateur 2D printers? Did we just jump to 3D printing because it was cooler (which I also admit is amaizing)?

I just want a basic 2D inkjet or laser printer that doesn't stop printing because magenta is low or doesn't waste ink to “clean” the print head, nor make up weird errors because it doesn't have access to the internet.

What about printers without ink? Would it be too hard/complicated to use a lower power laser (instead of a laser cutter) to burn/scorch a thin micrometric, if not nanometric, layer of normal everyday printing/copy white paper?

As a child, I remember scorching magazine/journal paper and all sorts of wood materials with my grandmother's handheld magnifying lens under the summer sun in the yard. I was able to draw stuff without burning some of the material completely.
