  1. Color laser printers run a page through the printing process four times -- once for each color (black, yellow, cyan and magenta). The combination of these colors allows a printer to reproduce the color spectrum. Some printers use four separate toner and developer units on a rotating wheel that lays down one color at a time. Other printers apply the colors to a plate before transferring the image onto paper. More expensive printers have complete printer units for each color.
