https://en.wikipedia.org/wiki/Laser_printing Color laser printers Fuji Xerox color laser printer C1110B Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more. Color printing adds complexity to the printing process because very slight misalignments known as registration errors can occur between printing each color, causing unintended color fringing, blurring, or light/dark streaking along the edges of colored regions. To permit a high registration accuracy, some color laser printers use a large rotating belt called a "transfer belt". The transfer belt passes in front of all the toner cartridges and each of the toner layers are precisely applied to the belt. The combined layers are then applied to the paper in a uniform single step. Color printers usually have a higher cost per page than monochrome printers (even if printing monochrome-only pages). Comparison with inkjet printers Manufacturers use a similar business model for both low-cost color laser printers and inkjet printers: the printers are sold cheaply while replacement toners and inks are relatively expensive. Color laser printers are much quicker than inkjet printers and their running cost per page is usually slightly less. The print quality of color lasers is limited by their resolution, typically 600–1200 dpi, and their use of just four color toners. They often have trouble printing large areas of the same or gradually changing color. Inkjet printers designed for printing photos can produce much higher quality color images.
