Ive been getting these in my feed too.

I remember a time when i bought a printer and it came with refillable ink cartridges which worked out significantly cheaper and better for the environment. And i could buy off brand cartridges that worked great too for cheaper.

The next printer i bought had microchips that identified the cartridges as being genuines so the cheap off brand ones didnt work anymore. And the refillable bit was gone.

That was easily 15 years ago. Why is this only just coming back up now. Its beena scam for over a decade. Maybe longer.

Let's not forget HP making an "update" that effectively self-destructed the printer for use if you don't use their cartridges. Evem after the public outcry and back pedaling by the company with a new bios update, my printer still "manifested" the same problem they intentionally introduced.

Replaced parts, tried other things, then just said "forget it" and replaced it with a more expensive color laser from a competitor. Happiness and reliable printing ensued.
