Have you considered using thermal printing as a starting place? The technology is old and free to use, parents have been expired for 20+ years at this point. It eliminates the need for ink entirely which seems like a big pro. The prints fade over time though, which isn’t great. But I have a thermal printer and use it often. Do you always need archival level artifacts printed? Anyway, it’s a cool idea. I wish you luck.
