Maybe? Sounds like a tricky thing to automate and then you also have solvent as an additional consumable. This is a problem even with huge industrial inkjets.

I mean, commercial printing is typically 300-600 DPI…

A bunch of rollers that need to be cleaned fastidiously if you want them to keep working.

That's just what happens when you have stuff dissolved in solvents.

That's direct thermal, not laser. Problem is direct thermal prints don't last very long and the paper is expensive. Thermal transfer uses expensive ribbons, and laser is super complex.
