This article (published in 2018) really conveyed the joy of engineering. It also frankly made me want to buy Xerox for my next printer: I've noticed a huge amount of similarity between different brands and I would not be surprised at all if they have a large amount of "shared IP" if diagnosing a jam requires a team of high-end researchers like as described.

Printing is an odd business. My grandmother was a typographer -- a layout artist, in the days before desktop publishing -- and had a unique combination of artistic skills and highly technical ones. The fundamental tension between those two aspects, together with an ever-present focus on minimising cost, makes for a cut-throat marketplace of multi-domain experts. It's an art we should celebrate. I took great pleasure in printing my PhD thesis, and the person who did the book binding both noticed and appreciated it, and as a result used machines and processes developed in the late 19th century to artistically produce the 10 hardback copies I had to have made. It's a wonderful mix of craft and care and I think a very misunderstood industry.
