These printers are the most common type of printers that are available in households.This process uses a xerographic printing process, which uses a cylindrical drum coated with selenium to print an image.
Inkjet is a type of printer that prints images by propelling droplets of ink onto the paper. 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. These printers differ from each other in various ways, including cost, technology used and maintenance. Laser printers are more commonly found in office settings, while inkjet can be used in office and home settings.

Laser printers are expensive units and require a dedicated place. 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. He modified an existing xerographic copier and fitted it with printing capabilities. The machine uses the data sent from the computer to create a raster line or scan line. The Raster Image Processing (RIS), typically 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 5,000 pages before replacement.
