A laser printer is a high-resolution printer that employs the use of the electrostatic reproduction technology characterized by photocopying machines to fuse the text and graphic images to paper. For every successful page printed, the printer’s controller circuitry receives the printing instructions from the computer and builds a bitmap of every dot on a page. The controller ensures that the print engine’s laser transfers a precise replica of this bitmap to a photostatically sensitive drum or belt. See light-emitting diode (LED) printer, resolution.
Technipages Explains Laser Printer
A laser printer uses an engaged bar or light to move content and pictures onto paper. When the paper goes through a laser printer, the laser beam fires at the outside of a round and hollow drum called a photoreceptor. This drum has an electrical charge (normally positive) that is turned around in zones where the laser pillar hits it. By switching the charge in specific zones of the drum, the laser pillar can print designs, (for example, content, and pictures) onto the photoreceptor.
In 1969, Gary Starkweather, had an idea to utilize a laser bar to “draw” a picture of what was to be duplicated straightforwardly onto the copier drum, in the wake of moving to Palo Alto Research Center (Xerox PARC) in 1971, Starkweather adjusted a Xerox 7000 copier to make SLOT (Scanned Laser Output Terminal). At that point in 1972, Starkweather worked with Butler Lampson and Ronald Rider to include a control framework and character generator, bringing about a printer called EARS (Ethernet, Alto Research character generator, Scanned laser yield terminal) which later turned into the Xerox 9700 laser printer. See Palo Alto Research Center (PARC).
Perhaps the greatest distinction with laser printers is that rather than fluid ink, they utilize a powdered toner component for printing. While laser printers have carried the higher ability to print, they have likewise presented new cost components. The present printers are advanced in terms of their technology and frequently likewise fill in as copiers, fax machines and scanners, yet they can likewise cost a considerable amount to keep up to work all the time.
Common Uses of Laser Printer
- Laser printers come in very advanced forms today with the ability to do just more than printing alone
- Laser printers are known to be quite expensive to maintain, hence the need for an expert operator.
- Laser printers can move content onto a paper
Common Misuses of Laser Printer
- You can only use the laser printer to scan documents and images
