What is ink expiration?
Basically ink expiration is a built-in date on which certain HP ink cartridges will stop working. Air ingestion and water evaporation can cause ink to change over time. In printing systems where the printhead and ink supply are separate, older ink can adversely impact the printhead and the ink delivery components within the printer. With ink expiration, however, HP can prevent this from happening.
