Hi, I have HP Jet Pro 8720 instant ink which bought in January 2017. If i buy HP-compatible ink cartridges, will it work? The cartridges I heard are locked to HP and will disable all the other non-HP ink cartridges. Will I get any help or instructions on how to make sure the HP-compatible cartridges can be installed? As you know in these difficult times, online learning I am looking for a cheaper alternative as I cannot afford to spend £78 on instant cartridges.
Your help is much appreciated.
Thank you.
