While many people choose to print in color, other individuals don’t need to print more than black and white. In laser printers, printing in black and white uses only the black toner cartridge and the white space on the page to produce the image. Printing in color uses all four toner cartridges—black, magenta, cyan and yellow—to create images, and since all are used, more toner is used per page. Generally, color print costs are higher than black and white. To determine which is best for you, and, consequently, what printer cartridge is best, consider the kinds of things you print most often. If most are simple pages of typed material, black and white will likely serve you fine. If you print a lot of photographs or pages with colorful graphics, color printers and toner cartridges are going to better fit your style.
