Well what’s different with 3d printer ?
I think 3d printer it’s very complicated compared to paper printer because 3d printer can print objects in 3d (need to calibrated in x,y,z position just to make it right) but paper printer just 2d
I think the right answer because no one want to make it because the business model of selling paper printer itself already at profit loss, printer company made profits from selling ink cartridges not from selling the printer itself
