What is the term for the printing method where ink is applied only when the printhead moves in one direction?

Unidirectional printing is the term that accurately describes the printing method where ink is applied only when the printhead moves in one direction. This technique involves the printhead moving across the page in a single direction to deposit ink, which can lead to more precise and higher-quality prints compared to bi-directional printing, where ink is applied in both directions.

In unidirectional printing, since the ink is only sprayed or applied on the forward movement of the printhead, it minimizes the chance of misalignment and allows for a more controlled application of ink. This method is often slower than bi-directional printing, but the focus is primarily on print quality and detail, making it suitable for tasks where precision is crucial.

Understanding this printing methodology is essential for anyone involved in printer technology or print services, as it can significantly affect performance and output quality depending on the requirements of the print job.
