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.

What about printers without ink?

Laser printers have existed for a long time and they don't use ink, but they do use toner. I'm gonna assume just scorching the paper has been proven to be a bad idea, because someone would have tried to market a toner-free printer by now otherwise.

My best guess is that it's very hard to scorch paper to a color anywhere near black without creating a serious fire hazard. Even if you could calibrate the laser just right, the next batch of paper could burn because it has a slightly different weight, texture, or composition.

You'd probably end up being special paper stuff something in it that turns black at a fairly low temperature. That's pretty common for things like receipt printers.

Zink Paper is an alternative but nowhere as cheap as regular paper+ink

The paper has several layers: a backing layer with optional pressure sensitive adhesive, heat-sensitive layers with cyan, magenta and yellow dyes in colorless form, and an overcoat.
