Abstract
An ink jet printing system includes an ink jet printhead which has an n-bit code representing a unique characteristic of the printhead formed on a substrate forming a part of the printhead. An n-bit data code is sent from a remote source to the printhead. If the data code matches the code on the printhead, printing operation is initiated. If the code is not matched, the print operation is inhibited.
