Ink and toner are consumables used in printing technology, each serving a distinct purpose based on the type of printer. Ink is a liquid-based substance used primarily in inkjet printers. It is sprayed onto paper through tiny nozzles to create text and images, and comes in various formulations, including dye-based and pigment-based inks, each offering different color vibrancy, fade resistance, and suitability for various paper types. Toner, on the other hand, is a fine powder used in laser printers. This powder, typically composed of plastic particles, pigment, and other additives, is electrostatically charged and transferred onto the paper, where it is then fused by heat and pressure to create a permanent print. Both ink and toner are essential for producing documents and visuals, and their quality significantly impacts the clarity, sharpness, and longevity of the printed output.
