My printer, which is a few years old (HP...which stands for "Here you Putz) needed some ink cartridges. Being a frugal type of person, I ordered some from Amazon, and failed to read the 1 star reviews. Long story short, the discount non-HP cartridges are problematic. My printer warned me they were not genuine, and allowed me to print a few pages. I was satisfied. A few weeks later, I decided to print a document, and the printer stopped due to "damaged" print cartridges. This inspired me to look up some of the shenanigans of the printer industry.
HP doesn't want you to save money on ink. They want to damn near just give you a printer, and then bend you over every time you need some ink. They do this by installing proprietary chips that tell the printer to stop, laugh at your discomfort, and point you to the line where they take your money at gunpoint. To make things worse, the other printer companies are following suit, and doing the same. Now, the big questions are whether HP downloaded software to defeat the cartridges, they're really not good, or maybe the printer has gone south. My options are either to buy a new printer, pay the exorbitant amount HP charges for cartridges, or pull out a Big Chief notepad and just scribble out documents like a demented old man in the 1800's.
