My mom bought a cheap HP printer/scanner several years ago and subscribed to their “instant ink” subscription which was actually surprisingly cheap (like $3/mo) but once the printer stopped reliably connecting to the internet and nobody could print wirelessly anymore with it, she canceled the subscription and HP DISABLED ALL OF THE INK CARTRIDGES. The cartridges themselves have wifi connections so HP can automatically send you new ink when they get low. What a scam.
