I don't think so. The current situation suggests that we really need an open-source printer, because otherwise there is no privacy at all.
The question wasn’t whether there was a need. The question was why there isn’t one. That agreement doesn’t prevent you or anyone else from making your own design.
You answered your question with "apart from the nozzle" It is the nozzle. Everything else is very simple to make because it is already done for 3d printers that are more complex than 2d printers(if you do not consider the nozzle). 5 years or so ago I made a 2d plotter with friends at my 3d printers community with the reverse engineering knowledge that we had about a specific cartridge with nozzles on it. Printing wit…

How about laser engraving tech? Can a laser engraver be tight focused to 300 dpi and power set (or sensed) to just make a mark on white paper? Does the positioning accuracy also need to be improved to get that 300 dpi? You'd never run out of toner at least. Edit, answered at least one question: yes engravers do 500 dpi routinely. Here's one: https://www.troteclaser.com/en-us/knowledge/tips-for-laser-u...
I would not consider an engraver for which you have to call to ask the price as "routine". From what I could find, the cheapest trotec is $16k second hand on ebay (and there is another from their cheap line for $56k second hand). You can hire somebody to handwrite everything you need for that kind of money. Also, high power lasers are consumables.

Given the availability and complexity, the question becomes "why bother." Microdots are an answer to that.
Then I'd ask, is there a legitimate purpose? Supposing the end goal is a totally open source chip foundry: yeah, you don't want microdots on your masks. Edit: oh god, and printers that won't do b&w without yellow dye available.

Why can't you 3D print a nozzle? Or are there electronics in there too?
I have Samsung CLP-310 Color Laser Printer from 2008. It was the last one ever, which you can force-reset so it does count how many times a color cassette been used. I can refill those cassettes from half liter buckets from ebay for €10. It is just incredibly reliable. One and only problem is that only the XP-windows Samsung printer drivers work truly well. But I have 2008 laptop for that.
I worked for a while in the R&D department of HP printer division. As @jacquesm said, good 2D printer costs peanuts. The amount of R&D in color quality, speed and other parameters is huge. There were a lot of teams involved: mechanical, electrical, software, chemical... And because of that investment, there are thousands of patents that the big players are continuously paying each other for. It's a very old market wi…
Because you can print 3D printer with 3D printer. You can make paper templates with paper template.

99% of FOSS consumers only care about free beer, hence the uptake on MIT like licenses.
Where did you derive that number from?
Hordes of complains about paying for something, followed by MIT like licenses based clones.
