Abstract
A manufacturer or the like provides consumable products used in an image forming apparatus with distribution information including a most recent license code and then markets the consumable products, and the image forming apparatus performs authentication processing by reading the distribution information from such consumable products. Receiving a connection request from an application executed by a personal computer, the image forming apparatus determines whether connection may be permitted or not by comparing the license code of the application included in the connection request with the distribution information provided to the consumable product.
