Abstract
A printing apparatus can reduce wasted power consumption, and prolong the life of an image forming section and fixing pressurizing rollers. It includes a printer control unit including a video controller and engine controller. According to a print reservation from the video controller, the engine controller controls a paper transport mechanism such as feed rollers, transport rollers and lifters, thereby feeding paper from a paper inlet designated by a printing condition. The engine controller controls a laser scanner unit to transfer a formed image to a sheet with a high voltage unit, and fixes it by a fixing assembly. It controls the paper transport mechanism to output the paper to the paper outlet designated by the printing condition. The image forming section and fixing pressurizing rollers are individually rotatable. Their rotation is stoppable individually without interference in a time from printing the first side to reversing and refeeding the paper.
