From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Perhaps we need an "open source" laserprinter?
I wonder if even just an open source firmware for printers could work.
Actually, I think it might take a whole "open source" company - the printer itself is sold assembled at a profit (Much more expensive than printers today) but it can be assembled from available plans and off-the-shelf parts. The control inside the computer would probably be something a lot like a Raspberry Pi.
The ink is provided at the actual cost, and the formula for the ink is available.
The firmware is downloaded from the host computer on printer power-up, so that can be fully open source- allowing the user to correct or add functionality. Perhaps driven by a high-level "printer language" that would make writing printer firmware easy to understand and update.
I was thinking someone could make a firmware like Tasmota but for printers that can be installed on many existing printers, and a company could make a printer that runs that is designed to run that firmware just like how you can get smart home devices designed to run Tasmota. Also, we just need printers that properly support IPP.
But first, you will need to discover how to pry the existing firmware off so many different kinds of printers. This, unfortunately, is probably a DMCA violation (bypassing a security measure, for example, the code that forces one to use only 'approved' ink supplies)
