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.
