The OpenPrinter project (see the CrowdSupply project’s page) aims to create an open source repairable printer. It has some interesting features.
I was starting to believe the project was dead but they gave some news on their progress today : https://www.crowdsupply.com/open-tools/open-printer/updates/progress-update-and-details-about-our-nomination-for-a-french-design-award.
I post it here since the project is lead by french people and would be an alternative to many printer manufacturer.
There are inkjet printer with ink costlier than blood /Liter, and there laserprinters, which, afaik even recollect unnecessary ink from the paper, back into the ink cartridge.
Laser is a lot more sustainable than inkjet.
