Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (), and transfers the image to paper, which …

Laser printers as well as LED printers rely on one and the same technology used at first in photocopying machines. This process is known as electrophotography and was invented in 1938 and developed by Xerox and Canon in the later 1980s. Electrophotographic process in laser printers, involves six basic steps: A photosensitive surface (photoconductor) is uniformly charged with static electricity …
