HP has been incorporating more electronics into print cartridges for no other reason than to maintain ridiculous prices for common soy-based ink.

I hope that the logic of recent Copyright Office / Library of Congress decisions is emulated here, that when a company attempts to reap high profits from proprietary hardware tricks, it doesn't remove consumer rights, nor restrict other manufacturers from duplicating function.

I bought 2 AIO printers from HP to find that, shortly after my purchases, HP stopped making the 02 ink cartridges required by my printers. They have become impossible to find so I did, what for me, was the unthinkable: I refilled my original HP cartridges with third party ink. My printers told me they knew what I had done and my warranty would not be valid if I continued. They also told me I might be irreparably harming my printers......

Everything works great and the refills cost next to nothing.

I now feel that if someone has bought the printer then they have the right to use the ink of their choice.
