Why no FOSS color pencil or pen plotter with robotic paper stack management (next sheet, and bonus: turn-over), ready to 3D print, flash onto pis, and forever replace the supply chain cumbersome ink and toner-based printing??

We can 3D print, why no easy common pencil/pen printer replacement plotters?!!

One of my old professors worked at HP and chatted about his involvement in putting ICs in ink cartridges. From what I remember hearing, each one is flashed with calibration data to improve the print quality.

Does anyone know if this is still true, or if it makes that much of a difference?

As much as I love giving the middle finger to a company as awful as HP, people need to stop supporting garbage companies like this and then this wouldn't be necessary.
