PRINTHEAD INCLUDING INTEGRATED CIRCUIT DIE COOLING

摘要

One example provides a printhead including a substrate and a fluidics structure attached to the substrate. The fluidics structure includes actuators for ejecting ink from the printhead. The printhead includes an integrated circuit die attached to the substrate. The integrated circuit die is for driving the actuators. The integrated circuit die is cooled by a coolant contacting the integrated circuit die and flowing through the substrate.
