Well… There is quite a bit of high precision manufacturing needed for the actual print heads… Something like a Dot Matrix straight from 1990s should be doable by people with appropriate CNC machines and shit, something like “Line Typers” (1950s-1970s automatic computer operated type writers) are manageable if you can precision mold metals
But an ink jet or laser jet? Naw big dawg that shit is complicated as fuck
If you can somehow manufacture the ink head, an ink jet printer is like 2 step motors and one really complicated print head on rails

Or if you can use existing cartridges, you would skip a lot of work. They have the print heads embedded in them nowadays.
