Laser Printers: LASER stands for Light Amplification by Simulated Emission of Radiation. A laser printer is the fastest and high quality non impact printer. It works like a photocopy machine. The laser printer transfers the image of output on paper using LASER technology and toner. Toner is and ink powder. Toner refill after low coloring but most printers print about more than 2000 papers on one refilling that is why there cost of printing is very low and they use low energy and make no any noise.
