Fascinating! I myself am partial to the Muji lay flat notebooks.

Question: how can I find a printer to make my own? I run a small business making staff paper notebooks. I want to make lay flat, thread + tape bound ones. How can I find a printer that can help me replicate? (I also want to launch a line of cheap mead-like notebooks, but similarly have trouble figuring out how to get those done.) most places will do spiral, wire-o, or saddle stitch with essentially copy paper but I’d like to be able to make these more specialized items.
