I don’t really understand why or how it’s happening, but my HP LaserJet printer connects to Wi-Fi less and less reliably every year. I want to upgrade to a color laser, but: (1) Wirecutter's current rec is for another HP, and (2) it's $750.
The HP inkjet I got in 1997 was far more reliable, even before we switched from parallel to USB. And it could print banners!
