The print engine is the essential component of a printer that carries out the actual printing process. It consists of mechanical parts responsible for transferring images onto paper. In inkjet printers, the print engine includes the print head with tiny nozzles that spray ink and a carriage to move it across the page.
This critical part dramatically affects the quality of printed output. Faster print engines generally offer quicker results but may compromise print quality. Conversely, slower machines take more time but tend to produce higher-quality prints.
Printers today use different types of print engines, such as thermal, piezoelectric, and laser. Each type has its strengths and weaknesses, making the choice dependent on factors like printer type, intended usage, and budget.
Print engines comprise three main subsystems: an input device for image data, one or more printing heads to put ink onto paper, and a controller to manage the printing process.
The printing heads play a crucial role in these engines by physically depositing ink or toner onto paper. The specific type used—thermal, piezoelectric, or inkjet—varies depending on the engine’s design.
Optimal print quality relies on a print engine that functions well. This ensures smooth movement of the print head and even distribution of ink. Without it, both aspects are at risk, resulting in inferior printing outcomes.
