You bought one of the printers that end with an "e". For example:

HP OfficeJet Pro 9025e vs HP OfficeJet Pro 9025

OR

HP LaserJet Pro M234sdwe vs HP LaserJet Pro M234sdw

The "e" printers support subscription based ink and require an internet connection otherwise they won't print.

- It says it all over the outside of the box

- It says it in the box on multiple sheets of paper in big text

- It says it when you are installing the driver

- It says it when you are purchasing the subscription

The cost of the printer is subsidized to some extent (similar to carrier locked phones) and they are subscription based printers.

I don't understand how HP is at fault here. Subscriptions are a shitty business model, but nobody forced you to buy a subscription based printer. If you didn't want that, then you should not have bought the "e" model, you made that decision yourself, ignoring all the warnings outside and inside the box, regretted it later, then blamed HP.
