What is the primary function of a Laserjet printer?

The primary function of a LaserJet printer involves using a laser to create high-quality prints by fixing toner to the paper surface through a combination of heat and pressure. In the printing process, a laser beam projects an image onto a rotating drum coated with a photosensitive material. The areas exposed to the laser become electrically charged, attracting toner (a powdery substance) to those areas. The paper is then passed through a fuser unit, where heat and pressure bond the toner to the paper, resulting in sharp text and images.

This process allows LaserJet printers to produce prints quickly and efficiently while maintaining high resolution and clarity. The use of toner rather than liquid ink contributes to the speed and quality of printing, making it distinct from inkjet printers, which rely on liquid ink. The other options describe different print technologies or functions that do not accurately represent what a LaserJet printer does.
