Abstract
In an implementation, a printhead includes a printhead die molded into a molding. The die has a front surface exposed outside the molding to dispense fluid drops through nozzles and an opposing back surface covered by the molding except at a channel in the molding through which fluid may pass directly to the back surface. The die also has a nozzle health sensor molded into the molding to detect defective nozzles in the printhead die.
