Printhead.
the inkjet engine that fires ink through nozzles onto the substrate
The array of nozzles that fires ink droplets onto the substrate under the RIP's instructions, the actual print engine of a digital press. Head model sets resolution, drop size, ink compatibility, and cost to replace, so the throughput and defect stories in this glossary trace back to which head a machine runs: Fujifilm Dimatix StarFire, Ricoh MH5420/5440, Kyocera KJ4B.
