I don't recall seeing a warning that these cartridges do not come with a chip required to use the product in my HP printer. The product comes with instructions, a cutting tool and tweezers to remove the chip from a used cartridge and place it in a new cartridge. It took me 15 minutes to figure out what I was doing. So this new cartridge works perfectly. The printer says I'm using a nearly empty cartridge. It didn't cause any printing problems.
