HP doesn't even sell the ink for my (relatively new) printer where I live.
Its on their U.S site, but I can't order from that since it asks for a ZIP code.
Most BS thing I had to deal with HP ink was region-locked ink. If you buy the European version of the US ink (it’s literally the exact same thing with a different label) it will refuse to work unless you change the region of your printer. Good luck going through HP support
