Abstract
A video signal generating apparatus for a laser beam printer including a dot counter which counts the dots along the horizontal side of a recording area, and a raster counter which counts the dots along the vertical side of the recording areas. In accordance with the outputs of these counters, a character pattern memory produces a character print dot signal, while a set value representing a ruled line size is calculated from the outputs of the dot counter and the raster counter, thus producing a ruled line signal. These two signals are combined to make up a video signal.
