The long, long road to a FOSS printer
The long, long road to a FOSS printer - programming.dev
I don’t have to tell anyone that commercial printers suck (with the possible exception of Brother, but how long will that last?). I’ve read people on here talk about the viability of making a FOSS printer. I’d like to keep these thoughts going. From what I remember, there are four main challenges, listed descendingly by their apparent difficulty: 1. Handling ink 2. Meeting legal regulations 3. Moving the moving parts 4. Patents Patent difficulties indeed should be avoidable, since decent printers have been out there for way more than 20 years, the usual duration of a patent. Moving the moving parts with the high precision necessary at first glance seems daunting, but I’ve read people say that this is a problem many people know how to solve. Meeting the legal obligations may ne trickier: Printer fingerprints? Aerosols? Other health and environmental hazards? Handling ink: From what I remember, this would be the main difficulty (unfortunately I can’t find that post or comment anymore). One should avoid the problem of creating an own cartridge & nozzle production by designing the printer such that it can use an existing cartridge model (one for which there are good third-party offers). Still, one would have to solve the apparently very difficult problem that the ink/toner has to be handled under very precise conditions, regarding things like flow velocity, drying rate, and perhaps temperature. In view of these challenges, I’ve started to think that maybe the best approach would be to try our best to find ex-employees of printer companies and convince them that they would be doing humanity a huge service if they were to contribute with whatever they legally can towards developing a FOSS printer. Also, I’ve wondered whether the time to do this may be running out: If even Brother one day starts to crack down on third-party ink/toner, all the producers for third-party ink/toner could eventually go out of business; so that one may successfully develop a FOSS printer, only to have no other ink in the stores than the price-gouged one, which was the reason to do all this in the first place. Do you have any corrections, specifications, or further thoughts? I’d love to hear them.
