If anyone wants to create an open source printer I think they would get some sizeable backing. I would take anything that can print text onto random A4 paper and takes reasonably cheap ink. There's not so much already in this space [1]. Just keep the goal simple and achievable. It's way too dangerous, but I often pondered a "zero ink" solution that burns text directly onto paper. Essentially a high-speed laser engraver. I could imagine given heat and fuel, you would want to limit oxygen, possibly by pulling a vacuum. I would also like to see what a modern take on a dot matrix printer could be like. [1] https://www.appropedia.org/Open_source_Inkjet_printers https://www.appropedia.org/Open_source_Inkjet_printers
