Explanation
Laser printers use an imaging drum (photosensitive drum) as a core component of the electrophotographic (EP) process. The drum is electrostatically charged, then selectively discharged by a laser to form a latent image. Toner particles adhere to the discharged areas, are transferred to paper, and are then fused by heat. Thermal printers use heat-sensitive paper. Inkjet printers spray liquid ink through microscopic nozzles. Impact printers (dot matrix) use pins striking an ink ribbon. None of the others use an imaging drum.
