All of that, including the interfacing are not related to patents.
It's not like there's some patent issue for using USB or wifi in your printer over whatever interface used in 2000 compared.
Or like there's a patent on using faster processor or more RAM in your printer (two things you've mentioned also).
Because as a layperson, I would not have thought a company could get a patent on clicking a button to purchase an item online.

This seems like a pretty strong statement, can you elaborate as to why solving paper jams wouldn't involve patented IP ?
Now that I've helped you out of the quicksand, let's do battle:
"[I feel like] it's not like there's some patent issue for using USB or wifi in your printer over whatever interface used in 2000 compared."
I could certainly try harder to finesse it, but I don't see any sensible place to insert a "YMMV" into any part of that sentence.
Do you really believe "researching" is needed?
Like, in every other domain and product category, a company can slap a faster processor and more RAM to the next iteration - as they do -, but this is somehow prevented in printers by patents?
I'd say the extraordinary claim that needs extraordinary evidence is not mine...
