Detailed explanation-1: -Answer: A color laser printer meets all of these criteria. Color laser printers print both black and colored documents and use toner powder instead of ink so it won’t dry up in between uses–plus no printhead to worry about!
Detailed explanation-2: -Powdered ink (toner) particles are then electrostatically attracted to the charged areas of the drum that have not been laser-beamed. The drum then transfers the image onto paper which is passed through the machine by direct contact.
Detailed explanation-3: -A laser printer does not require ink but it uses toner, which is made up of plastic and iron particles that are heated and melted to the paper by a fuser unit.
Detailed explanation-4: -A semiconductor diode laser is currently used in laser printers as the light source.
