Okay, that is garbage... I don't know what to say other than to also look at Amazon reviews... But yes, totally misleading and you would never know until you get the printer in hand and purchase the subscription.
It depends on the cartridge. If you buy the subscription, you get special subscription cartridges that will stop working if you cancel, but they are included in the subscription price.
If you buy normal cartridges, they will work until they are empty.
If you paid money for a cartridge that doesn't work without a subscription, you got scammed by the seller, not by HP.
