Abstract: A method of and a system for generating a printing ID code representing product ID information to be printed on products based on an identification information of a specific one of the products which is stored in a memory accompanying the specific product. The printing ID generation is performed by converting the identification information read in by an information reading section into an alphanumeric ID code by a notation system of base N so as to have a number of digits less than an encode ID information, converting a part of a numeric code representing a production date of the product into an alphanumeric date code by the notation system of base N and combining the alphanumeric ID code and the alphanumeric date code as a printing identification code.
