A laser printer is a type of computer printer that uses a focused laser beam and electrostatic technology to produce text and images on paper. Instead of spraying liquid ink like inkjet printers, laser printers use toner, a fine powdered ink, which is transferred onto paper and fused with heat to create permanent prints.

When a document is sent to the printer, the laser beam draws the image on a rotating photosensitive drum using electrical charges. Toner particles stick to the charged areas on the drum, and the toner is then transferred to paper. A heated fuser unit presses and melts the toner into the paper to produce a durable print.

Laser printers are widely used in offices because they offer high printing speeds, excellent text clarity, and low cost per page compared with many inkjet printers. They commonly print 20–40 pages per minute and can achieve resolutions of 600–1200 dpi or higher for crisp documents.

Many modern laser printers are multifunction devices that include printing, scanning, copying, and sometimes faxing, along with connectivity options such as USB, Ethernet, and Wi-Fi for convenient office or home use.

Laser printers are ideal for business documents, reports, invoices, and high-volume printing tasks, making them a popular choice for offices, schools, and professional environments.
