It is not very often that a 15 year old machine is still on the market. Even if someone does have an ancient device, the parts that would need to found to keep it running would eventually stop being made and sold. However, it is a different story with the HP Deskjet 1600. This inkjet unit was introduced to the United States in July of 1995 and still to this day is being used in many homes and small offices. Don't forget about the 1600Cn, which offers a 500-sheet paper tray, or the 1600cm which is compatible with all operating systems. The HP 1600 only works with Windows.
