Whilst HP cares about their customers and your satisfaction, they also above all else are a business and need to protect themselves. This would mean that the printer is locked to instant ink services and any installed from that point would also be locked to the printer. The printer can also be locked if purchased a new printer that can be used on the instant ink service and the screen prompt asked you if you would like to use the service and you clicked yes.
If you see the message HP cartridges locked and you are experiencing this issue then it’s very likely that you have recently had a printer update to enable cartridge protection or you have a brand new printer with this feature already built in. These updates can change the way your printer operates or as in this case add new features.
With new printer models that are continuously connected to the internet, software and firmware (permanent software that is built into hardware devices) updates are routinely installed.
