A printer has a shift register, an emission-timesetting section, a laser diode, and a drive section. The register supplies the emission-time setting sectionwith bits representing consecutive pixels including atleast one black pixel. The emission-time setting sec-tion determines the period of time during which thedrive section is to drive the laser diode, from thepixel patterns represented by the bits supplied fromthe register, and outputs an emission-time signal whichrepresents said period of time. In response to theemission-time signal, the drive section drives thelaser diode for the period of time, whereby a blackpixel of a desired size is formed on a printing medium.
