Color printer are those printers which are able to print more then one/single color. Many of these machines work on the CMYK color-model, 4 basic color i.e. the cyan, black, Yellow and magenta. The CMYK model prints all these basic color close to each other and then stimulates most of the other colors(except fluorescent yellow color) Further, some low-rated and low-priced color printer use only 3 basic color- yellow, cyan and magenta. Such machines will not be able to print the true black color and also the colors will tend to look faded.
Color printers are mostly used in printing books, paper materials and magazines. color printers are also capable of giving instant print of the given data.
