摘要： A printing apparatus is controlled to generate a pulse signal so that a print medium conveyance speed detected by an encoder comes close to a target speed. The duty of the generated pulse signal is calculated every predetermined timing. When a sensor detects the leading end of the print medium, the duty of the pulse signal input to a feed motor is stored in a memory. It is determined whether the difference between the calculated duty and the stored duty has exceeded a predetermined value. If the difference has exceeded the predetermined value, supply of the pulse signal stops. When supply of the pulse stops, a conveyance roller is driven.

摘要： A 2-pixel averaging unit (101) halves an input image in the subscanning direction, and a multi-level error diffusion unit (102) performs multi-level error diffusion processing. A 2-pixel reconstruction unit (103) replaces each pixel with two pixels adjacent in the subscanning direction. A density value exchange unit (104) exchanges pixel values adjacent in the subscanning direction in each of 2×2 pixel blocks arranged in a checkered pattern in the image after replacement. High-density blocks each serving as a set of high-density dots and low-density blocks each serving as a set of low-density dots can be generated as 2×2 pixel blocks. The exposure region can be concentrated in PWM conversion.
