Abstract: A disk printer controller for controlling a disk printer in the application of a printed image to the non-recordable label face of a compact disk, the disk printer controller having a scanning assembly and an electronic control system for controlling the sequence of operations of scanning and printing. The electronic control system includes a host computer and computer software connected to the scanning assembly. Prior to the printing operation, the scanning assembly scans a portion of the label face of the compact disk, and the disk orientation relative to the printer is calculated. The image is rotated and adjusted in computer memory and is finally sent to the disk printer for application on the non-recordable label face of the disk at the proper location and angle.
