Second hand purchase

[Manytimes1]

I just purchased a friends printer because they upgraded and it seemed affordable to me, but I am having a hard time printing due to their enrollment in hp ink, can I possibly unenroll them so I can use my printer?

I do not have an instant ink printer. My understanding is that if you run out of ink, or you cancel your subscription, you can use genuine Hewlett Packard cartridges either original or refilled. They must have an HP chip in the cartridge.
The below type is unlikely to work.

Note that this is a peer to peer forum and I am just the messenger of this bad news: Instant ink cartridges can only be used when the ink subscription is active.  

While HP Instant Ink printers can be used with no subscription, select HP Plus printers may require a subscription to operate.

For general help for new router or printer please refer to this article in our printer database.

Please provide the exact model name of the printer for better assistance as I may be able to find videos to show how to connect or fix the problem. A printer can be a PRO or a PLUS or have the letter 'e' after the number and that can make a big difference. Some printers with the same number ID could be a LaserJet, Deskjet, or Officejet.
