In the end it somewhat boils down to pure greed. Instead of stabilizing production costs and/or reusing generic components to ease up manufacturing and repair - HP, Epson, Canon, Dell, Samsung, Kyocera and others try to hype their products with whatever tech stack is currently in trend. "growth hacking" is literally their job description.
There eventually will be a ChatGPT printer on the market. It's inevitable due to what kind of people manage a printer business: It's not the type of people that know how to build printers anymore.
I unfortunately discovered that my brand new Brother printer can only communicate over 2.4 GHz wifi, which conflicts with the 5 GHz my phone requires (my router can only do one at a time, and there's no way I'm switching as needed). So USB it is.
It's one of their cheapest inkjets (MFC-1010DW), but I selected it for features more than price. Wish I had read the documentation. I would have purchased the next model up.
Nicely compact compared to the ~10 year old Canon that died recently.
And/or documented microcontrollers that are purchasable in the states?
Won't 2.4GHz have better range anyway over 5GHZ?
