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?
I think that 2.4GHz having longer range is a myth. When I worked on WiFi for Google Fiber we tested it pretty extensively and didn't see any common building materials that attenuated 2.4GHz more than 5GHz. Historically, the problem was that routers often selected low-power channels for 5GHz. If you use a channel where the maximum power is permitted, 5GHz is just as good.
The 5GHz band plan is kind of complicated. You will want to ensure that you get a 160MHz channel. How you accomplish that varies by region, unfortunately.
