The "no printers" is a positive, unless it's a laser printer from the 2000's.
(Someone should make an open source laser printer.)
it's ironic how the worst piece of proprietary software made to trick customers is in the printers, the software straight up just lies on there being no ink
Even worse is, you need to regularly use the inkjet printer, or the cartridge clogs.
Are you talking about the office or the sauna?
I am devastated that I got rid of my 2000s HP LaserJet (with Ethernet). Only flaw it had was that it didn't have a duplexer.
I think the problem with creating a printer is that you have to have a reliable source of ink that will not sue you if you use their designs
Toner isn't that hard to source.
The real issue is precision accuracy. Keeping things to 2D might sound easier than 3D, but 3D printers don't need the level of accuracy and precision that 2D printers do. 300dpi means dots every 85 microns. A very carefully tuned FDM 3D printer can get around 50 microns, but see below for the gory details:
https://3dprinting.stackexchange.com/questions/10349/do-3d-printers-really-reach-50-micron-0-05-mm-accuracy
Either way, 300dpi isn't particularly impressive for a paper printer. Usable, but there's going to be some blockiness to text, and graphics won't be good at all. 600 or 1200dpi is more like it. Which means we take that 85 microns and cut it in half, and maybe cut it in half again.
If we're talking color, than our difficulty increases 4x (because there's four cartridges for CMYK). They all have to be aligned properly to mix the colors to get a good image. We're also definitely headed towards 1200dpi at a minimum for good results.
Now, an open source plotter would be interesting. Not great for text documents, but useful for diagrams.
That's the nice thing about laser printers, lasers are super accurate. You're not moving any significant mass around. All you're doing is rotating a mirror and moving that beam in a single axis. If you continuously spin the mirror then your accuracy depends on how fast you can turn the diode on and off.
With laser printers, all you need is toner, which is much more easily available.
Printers are a restricted item in most countries when it comes to manufacturing and producing due to counterfeiting, as such any open source printer you could produce would most likely run a foul of local laws due to the ability to remove anti-counterfeiting requirements.
