Dot matrix printer

Design[ edit ] Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet or solenoideither directly or through small levers pawls. It is pierced with holes to serve as guides for the pins. The plate may be made of hard plastic or an artificial jewel such as sapphire or ruby. The portion of the printer that contains the pin is called the print head.

Dot matrix printer

Laser printer is a type of printer that produces high quality text and graphics by passing a laser beam on plain paper. This process uses a xerographic printing process, which uses a cylindrical drum coated with selenium to print an image.

Inkjet is Dot matrix printer type of printer that prints images by propelling droplets of ink onto the paper. These printers are the most common type of printers that are available in households. Dot Matrix printers is a type of printer that produces documents by having a printer head run back and forth and strike against an ink soaked ribbon to produce characters.

Maintenance level is high for the device and is also expensive. Laser printers are more common in black and white, while colors printers cause extra. Laser printer was developed at Xerox in by Gary Starkweather. He modified an existing xerographic copier and fitted it with printing capabilities.

The printer works similar to a photocopier. The machine uses the data sent from the computer to create a raster line or scan line. The Raster Image Processing RIStypically built into the printer, creates a bitmap of the final image in the raster memory. After this, an electrostatic charge is applied to the photosensitive drum.

The system also applies AC bias to the roller to remove any previous charges and a DC bias on the drum surface to ensure a uniform negative potential. A laser is then fired on the electro statically charged light-sensitive drum.

The drum then attracts the toner in the places the charge is still present. The drum then becomes hot and fuses the toner to the paper, which then produces the image.

Laser printers are quite extensive cleaning incase of jams and requires maintenance. However, one toner can produce up to 5, pages before replacement. Inkjet is a type of printer that produces images by propelling droplets of ink onto the paper.
