It has been since long in my mind to know how does a Standard Laser Printer works.. How does it receive a print request and how it print on a paper when there’s nothing like Ink .. there’s only a black powder… and that to within a fraction of a second..
Please help me understand for my above question

It receives a print request from the print spooler that resides within the computer that sends the request, via a medium of USB, FireWire, or network. Then once all the printing data is received, it will start up the laser, and apply the toner, using the laser, on the rotating drum inside. Then, a piece of paper will be drawn in, and prints by pressing the printed image on the drum to the paper.
Works by a laser charging the drum in the print area with positive or negative ions, cant remember which now, been a few years. The toner (the black powder) is attracted to this charge and is transferred onto the drum. The paper is then charged as well and will attract the toner from the drum when the drum rolls over the paper. Then the paper passes through a heating element where the toner is bonded by heat to the paper.
