Question about HP OfficeJet Pro 9025

With 2 months of free Instant Ink.
What is Instant Ink?
When you need ink, your printer automatically requests more ink from HP. The ink supply comes before your old ink is used up.
How does it work?
You have an Instank Ink compatible HP printer.
Register your printer here: https://instantink.hpconnected.com/ch...
You will receive a confirmation email about the successful registration.
Billing and service will only start after you have inserted your first HP Instant Ink cartridge.
When your ink supply runs out, your printer will request a refill in time.
You can cancel at any time
Refunds will be issued upon successful enrollment in any Instant Ink rate plan. You can also sign up for the free plan (15 pages / month at 0.- monthly fee). This way you will not only print 15 pages per month for free, but you will also get 30.- cashback without paying a cent.
