Abstract
Abstract Printers (1) selectively connected to a computer terminal device (2) is identified. By controlling the printer (1) using a dedicated correction data (204), a quality of the printing image is improved. As an identification data of the printer (1) connected to the computer terminal device (2), a printer ID (206) is checked. By reading the correction data (204) corresponding to the printer ID (206), the head shading process is performed for the printer connected to the computer terminal device (2) using the correction data (204).
