PURPOSE: To easily change the printing by preparing the label information to be processed by a printer, preparing the label information by a data- processing system for applying the information to the printer, and providing the printer with an information carrier comprising the print according to the label information.

CONSTITUTION: An inkjet printer comprising an printer head 19, is mounted on the circular area 2 of a disc-shaped information carrier 1. The printer head 19 is driven by a stepper motor 22 through a driving member 21 along a guide member 20 in a radial direction. When the printing is to be executed on the circular area 2, the printing is performed from an inner edge of the circular area 2 to an external edge thereof in a radial direction by the inkjet printer, and the printing is executed in a printing area 5 by the printer head 19 moving in the area 5. Then the disc-shaped information carrier is rotated by a given angle, and the printing is executed in the radial direction by the printer. This process is executed by one rotation of the information carrier 1, whereby the printing is executed on the total circular area 2.
