    摘要： Provided is an inkjet printhead integrated circuit that has a wafer substrate that has an ink passage, and a nozzle plate supported on the substrate by side walls to define an ink chamber supplied with ink via the ink passage. The nozzle plate has an ink ejection port corresponding to the ink chamber. A heater element is bonded to the nozzle plate inside the chamber for vaporising ink to generate a vapour bubble that ejects ink through the ejection port. The heater element is bonded to the nozzle plate with a low thermal product layer. The thermal product thermal product is less than 1495 Jm−2K−1s−1/2, the thermal product being (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer.

    摘要： A printhead is provided having fluid ejection nozzles, heaters corresponding to each of the nozzles respectively, with each heater heating printing fluid to cause ejection of a drop of the printing fluid through the corresponding nozzle, and circuitry for generating electrical drive pulses having variable power and length for energizing the heaters. The drive pulses are generated to have less energy than the energy required to heat a volume of the printing fluid equivalent to the drop volume, from the temperature at which the printing fluid enters the printhead to the heterogeneous boiling point of the printing fluid.
