I've using HP instant ink in my printer for a few years without problem but now at 15pence per page I decided to unsubscribe
Now I discovered that HP controlled the printer. First I could not replace the cartridges until the subscription ended. Now I find the replacement cartridges don't work, first the tricolour which i replaced with a compatible cartridge, then replaced it again. Now it works but the blank ink cartridges that I tried, don't work. I tried cleaning them but cannot even print an alignment page as the black ink which shows as full on HP smart software does not work, a test page all black comes through as blank. The original HP instant ink cartridges don't work. HP have control overy printer but trying to contact them seems no-go.
So I resort to buying a refurbished printer.
Spoke with a friend who had same problem after stopping instant ink subscription
Whatever she tried failed so her printer got binned
