This is a most excellent place for technology news and articles.
So never update my firmware then, got it.
I couldn't afford a Brother, but my Canon MG3620 works phenomenally with 3rd party ink. Another thing I like is that the software is delightfully stuck in the 90s. Simple and straightforward cause it literally hasn't changed since I was a kid. Yet you still get modern features like wireless and mobile printing, as well as borderless options. Everything I need a printer/scanner combo to do, and nothing more.
Idk why anybody with a pc would even connect them to wifi tbh.
So I can keep it in a central location since there's no ~~food~~ place for it in the office, and print being able to quickly print something from my phone is convenient (like a 4x6 photo from my phone to give to a visiting family member on the spot).
FWIW you can always disable wifi if you don't need it.
Gotta have a food place for the printer.
100% essential.
