This service seems to send a new ink cartridge when the current cartridge is running low. The monthly price depends on how much you print, and there is a free tier that allows for 15 pages/month but you will be charged $1/10 pages if you print more than 15 pages. It seems you need to provide a credit card even for the free tier. https://instantink.hpconnected.com/ https://instantink.hpconnected.com/ https://support.hp.com/nz-en/document/c03767640 https://support.hp.com/nz-en/document/c03767640 They seem to brick your cartridge to prevent the plan being cancelled just after they send you a cartridge, which could be done on the free tier. I don't like it in theory but it makes sense they would disable it.
