Electrostatic digital printing is the process by which laser printers apply images to paper. Inside the laser printer, a laser beam passes over an electrostatically charged drum; this laser beam changes the static charge on the drum to represent a portion of the image (be it text or graphics) sent to the printer. The drum then collects toner from the toner cartridge and the toner clings to the charged portion of the paper. The final step fuses the toner to the paper (if you’ve ever cleared a jam out of a laser printer and the toner dust wiped right off the page, the paper jammed before the fusing process).
