Abstract:
1. A printing system comprising an electrical interface for ink pens of an inkjet printer, the electrical interface comprising: a first group of electrical contacts; a second group of electrical contacts, said second group of electrical contacts being arranged in an identical configuration as said first group of electrical contacts, wherein the electrical contacts are configured to physically contact corresponding electrical contacts when one of the ink pens is installed in the inkjet printer to electrically interface the pen and inkjet printer, and wherein the first group of electrical contacts and the second group of electrical contacts provide an interface for different, respective pens; and a number of electrical interconnects, in which each electrical contact from said first and second groups of electrical contacts is connected to one of said electrical interconnects via a conductive trace; in which at least one electrical contact from said first group of electrical contacts is connected to a same electrical interconnect as at least one electrical contact from said second group of electrical contacts.
