Question about HP Smart Tank 7305

The HP Smart Tank 7305 says: "The savings plan is already included Get up to 12,000 black pages or 8,000 colour pages with Original HP ink, which is included." Nowhere does it say what you physically get. My question: what is physically included? Is the ink included or do you have to order it separately from HP, even if it's free? Many thanks in advance for the answer(s).
