Ah, another thrilling episode of "The Printer Wars".
FWIW computer forums generally are NOT flooded with topics about computers, printers or other peripherals that just work.
But I will attest to the trouble-free use of a series of HP Officejet AIO printers over many years. My current Officejet 9015e was a breeze to install (LAN for desktop, wifi for laptop), works great, and prints great under daily use. And - despite having an extended warranty - I have not needed HP support in many years.
And this is WITHOUT their "Instant Ink" or "HP Smart", which I do not need.
Like Dan, I buy only HP ink, as it's not worth being penny-wise and pound-foolish to save a few dollars amortized over the life of the printer.
Since the OEM printer manufacturers make their $$ from the ink/toner, not the hardware, it's certainly their prerogative to discourage use of generic, off-brand, cheap replacement.
If one objects to that idea in either principle or practice, then there are certainly many other brand options.
Different strokes (of the printer cartridge <pun intended>) for different folks.
