===Laserjet===

This printing method uses a laser to "paint" the desired image onto a photosensitive imaging drum. Toner is then picked up by the drum, and transferred to the paper.  Heat an pressure are then applied to the paper to fuse the plastic-based toner to the sheet. Black printer one go through this process once, but color printer must do so four times.  There are four photoreceptive drums, one is used for each color--yellow, magenta, cyan, and black.  Each drum prints its color onto a belt, then a transfer roller moves the toner to the paper. The printing process is as follows:
