Abstract: A user operates the operation panel portion 6 and selects an image quality mode in a pre-stage of carrying out CD-R printing. If an operation of commencing CD-R printing on the operation panel portion 6 is enabled, the CPU 16 causes the scanner unit 21 to scan a sample CD-R 25 and takes in the image data. The CPU 16 causes the taken-in image data to be subjected to an image working process and masks pixels not required to be printed. The ASIC 20 transfers the processed image data to the printer unit 22 and executes CD-R printing. At this time, the CPU 16 carries out scanning and printing at a resolution responsive to the image quality mode.
