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. [ 1] The drum then selectively collects electrically charged ...
HP introduced the mass-market laser printer, the LaserJet series II, in March 1987. The HP LaserJet II was designed as a laser printer with correct order page output as opposed to being leveraged from the Canon PC-20 personal copier. [6] The HP LaserJet II used PCL4, improved features, more memory and fonts for a market price of $2,695. [6]
Laser. A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission ...
Laser printers use a toner cartridge that contains powder instead of ink. These devices use static electricity to attract and imprint toner onto the paper through heat. Unlike ink, toner can sit ...
In computing, a printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. [1] While most output is human-readable, bar code printers are an example of an expanded use for printers. [2] Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. [3]
Toner cartridge. A toner cartridge, also called laser toner, is the consumable component of a laser printer. Toner cartridges contain toner powder, a fine, dry mixture of plastic particles, carbon, and black or other coloring agents that make the actual image on the paper. The toner is transferred to paper via an electrostatically charged drum ...
Toner is a powder mixture used in laser printers and photocopiers to form the text and images on paper, in general through a toner cartridge. Mostly granulated plastic, early mixtures added only carbon powder and iron oxide; now there are mixtures that contain polypropylene, fumed silica, and various minerals for triboelectrification. [ 1]
