There is apparently a printer that can use spent coffee or tea leaves to print. I love this idea but I would not buy a printer when so many are being thrown away. I pull them out of dumpsters with intent to repair them. So the question is, can they be hacked to work with coffee or tea?
Canon actually disclosed how to hack their cartridges as a consequence of a semiconductor shortage due to coronavirus. So this suggests #Canon could be a candidate for this hack. Has anyone tried it? How precisely do we have to match the viscosity of homemade ink to the original ink?
An even better concept would be a printer that brews your coffee and automatically sucks the grounds down into a reservoir to make ink from. 😜 And then filters the dry grounds into a container you could transfer to your compost bin.
