Abstract
An apparatus and a method are provided which can control an intensity level of an exposing device so that a desired pixel density is consistently disposed on a correct location on an image recording medium. Specifically, within a printing apparatus, even channel circuitry controls the intensity level of the exposing device during exposure of even numbered pixels on the image recording medium and an odd channel circuitry controls the intensity level of the exposing device during the exposure of odd numbered pixels on the image recording medium.
