A printer has a shift register (4), an emission-time setting section (5), a laser diode (62), and a drive section (67). The register (4) supplies the emission-time setting section (5) with bits representing consecutive pixels including at least one black pixel. The emission-time setting section (5) determines the period of time during which the drive section (67) is to drive the laser diode (62), from the pixel patterns represented by the bits supplied from the register (4), and outputs an emission-time signal which represents said period of time. In response to the emission-time signal, the drive section (67) drives the laser diode (62) for the period of time, whereby a black pixel of a desired size is formed on a printing medium.
