It is a hard problem, but it is also largely a solved problem since literally decades ago. If you were to start from scratch, you'd need to reinvent all of those things, which undoubtedly would make any such endeavor not worth it.

Of course, that doesn't make it worth it for just anyone to start making printers. But we see time and time again that where they fail nowadays is in UI, integration, and business models.

It's similar to the post on the first page about USB-C hubs, and graphics cards, and earphones. Typically you buy them as OEM stuff - very very few go through the trouble and design earphone drivers (loudspeakers) from scratch (etc). That, and reference designs. Visiting Shenzhen is an eye opener, browsing Aliexpress too :).
