Abstract
The present disclosure relates to an inkjet printing system that includes an inkjet printhead having a plurality of electrical contacts. The plurality of electrical contacts include address contacts and enable contacts for enabling drop generators and drive current contacts for providing drive current to enable drop generators for selectively ejecting ink therefrom. The printing system includes a printing device having a plurality of electrical contacts including address contacts, enable contacts and drive current contacts. The plurality of electrical contacts are configured to establish electrical contact with corresponding electrical contacts on the inkjet printhead upon insertion of the inkjet printhead into the printing device. The printing device provides periodic address signals and enable signals to the address and enable contacts one the printhead. In addition, the printing device selectively applies drive current to accomplish forming images on print media.
