Laser printing is an electrostatic digital printing process that rapidly produces high quality text and graphics by passing a laser beam over a charged drum to define a differentially charged image. It employ a xerographic printing process.

A laser printer uses a laser beam to create an electrostatic image on a drum, which then attracts toner to form the desired print on the paper. The laser in a laser printer is typically a semiconductor laser diode.
Ozone is a gas produced by some laser printers during the printing process. Ozone is released when the printer's high-voltage corona wire interacts with oxygen in the air. Exposure to high levels of ozone can be harmful and should be minimized by ensuring proper ventilation when using laser printers.
Dot matrix printers are typically used with carbon copy paper to create duplicate copies of documents. The impact of the printer's pins against the paper transfers the ink from the original document onto the copies beneath it.
Teflon is a non-stick coating used in some printer components, such as fusers and rollers. It helps reduce friction and prevents paper jams by ensuring smooth paper feeding and preventing toner from sticking to the components.
Neon is used in medical equipment like neonatal incubators and in high-voltage equipment for electrosurgery due to its inert and non-reactive properties. It is also used in laser surgery as a cooling agent for the laser.
Xerox toner is a fine powder used in Xerox laser printers and copiers to produce high-quality text and images on paper. It is made up of pigment particles mixed with polymer resin, which is fused onto the paper through a heating process known as laser printing.
