What is the term for the component that directs ink onto the paper in an inkjet printer?

The correct term for the component that directs ink onto the paper in an inkjet printer is the printhead. The printhead plays a crucial role in the printing process, as it is responsible for turning the ink into tiny droplets and applying them onto the paper in precise patterns to create images or text. It typically consists of a series of nozzles, each of which ejects ink at high speed to ensure a high-quality print output.

In contrast, while the nozzle is part of the printhead and plays a role in dispensing the ink, it is not the overarching term that encompasses the full mechanism. The cartridge contains the ink supply but does not interact directly with the paper. Rollers are involved in feeding the paper through the printer but do not contribute to the actual printing of the ink. Each of these components has its function, but the printhead is the primary part responsible for the application of ink onto the media being printed.
