A laser printer is a type of printer that uses laser technology to produce high-quality text and images on paper. It works by using a laser beam to create an electrostatic image on a rotating drum, which then attracts toner (a fine powder) that is transferred onto paper and fused with heat. This process allows for fast printing speeds and sharp, clear output. Laser printers are commonly used in offices and homes due to their efficiency and cost-effectiveness, especially for printing large volumes of documents. They typically have a higher initial cost than inkjet printers, but the cost per page is lower, making them economical for regular use.
