laserwriter pro 630

A semiconductor diode laser is currently used in laser printers as the light source.

LaserWriter (March 1985), included 13 fonts in ROM and 300-dpi resolution.

The key parts of the printer include, toner cartridges, image drum (also known as drum unit or photo-conductor), transfer roller or belt, fuser unit, laser, and mirrors.

A laser printer is a popular type of computer printer that uses a non-impact photocopier technology where there are no keys striking the paper. When a document is sent to the printer, a laser beam “draws” the document on a selenium-coated drum using electrical charges.

Lasers produce a narrow beam of light in which all of the light waves have very similar wavelengths. The laser`s light waves travel together with their peaks all lined up, or in phase. This is why laser beams are very narrow, very bright, and can be focused into a very tiny spot.

The HP LaserJet was the first desktop laser printer, introduced in 1984 at about $3,500. Nothing like it existed previously, and it created a totally new printer market—similar to what the HP-35 handheld calculator had done 12 years earlier.

The IBM 3800 is a discontinued continuous forms laser printer designed and manufactured by IBM. It is significant as a product because it was both the first laser printer manufactured by IBM, and the first commercially available laser printer.

Common features for laser printers include color printing, copying and or sorting capabilities, industrial metal housing, user controls, indicators, application software, and cutters. Laser printers with color printing are capable of color output in addition to monochrome output.

Laser printers are machines that melt toner powder onto paper to create a print. Laser printers are more expensive than inkjet printers upfront and uses pricier toner cartridges but is still a more economical option in the long run with its overall lower cost per page, faster print speeds.

The main advantages of laser printers are speed, precision and economy. A laser can move very quickly, so it can “write” with much greater speed than an ink jet. And because the laser beam has an unvarying diameter, it can draw more precisely, without spilling any excess ink.

A fiber laser uses an optical fiber doped in rare earth metals to amplify the laser beam. Because a solid strand of fiber is used to generate a high-energy laser beam, a fiber laser is classified as a solid-state laser.

This was developed as far back as 1962, and it creates the laser light via small crystal plates that are supplied with stimulating energy from a power source; hence, it is pumped by electrical energy. As a result, the diode laser is a semiconductor laser which, therefore, defines its own particular type of laser.

Laser diodes, fiber communication systems, and laser speed meters are class 1M lasers.
