The Continuous Ink Supply System (CISS) for the for HP simply fits into your existing printer replacing the need for expensive printer ink cartridges with a simple but very effective high quality bulk ink delivery system.

Providing a continuous supply of ink to the printer without the need to replace cartridges, the continuous ink flow system works by using a vacuum seal, preventing leakage and loss of ink supply to the ink cartridges

Once you have used the initial supplied high quality dye-based ink, the ink tanks can individually be re-filled with compatible ink very easily. You only need to top up on colours that require it.
