Who has so much free time? Easy solution:

- return cartridges since they do not work in "compatible" printer. Consumer laws do not care about small print or region locks

- go to unauthorized shop and have original cartridges refiled. I recycled cartridge like that for several years.

Not sure refilling works with HP’s DRM-equipped cartridges. I think they will refuse to print once their counter shows 0, no matter if there’s ink inside.

My dad used to be in the refill business selling parts, inks and all needed to get it done. Im not sure about this particular model but the DRM can be worked around in a couple of ways: swapping for a 3rd party drm chip, using a reset device or some older models just click “print anyway”.
