Toner powder is a fine, dry mixture of plastic particles, carbon, and colorants used in laser printers and photocopiers to create printed text and images. When printing, the printer's laser beam electrostatically charges certain areas on the drum, attracting the toner powder, which is then fused onto paper using heat and pressure. Available in black and CMYK colors (cyan, magenta, yellow, and black), toner powder produces crisp, smudge-resistant prints that are ideal for high-volume needs. It’s commonly found in replaceable cartridges but can also be refilled in certain models. Toner powder is favored in offices and businesses for its efficiency, long-lasting prints, and ability to produce sharp details, especially for text documents and professional-quality images.
