HP have updated their printers to ban ‘non-HP’ cartridges
Not only this, but our HP Pagewide inkjet machine will even refuse to use <i>genuine</i> ink if it’s “out of date”. I.e, its manufacture date was more than a couple of years ago. Also consider that the ink can sit on the shelf at the store or Managed Service Provider for this entire time and therefore go into landfill without ever being used in a machine.
