PROBLEM TO BE SOLVED: To solve problems that in a configuration in which an external device alternatively processes transferred print data, a main body device necessarily analyzes all print data in order to determine whether or not print data includes a font which cannot be processed in the main body device, and thereby processing load on the main body device increases when the main body device determines the existence or non-existence of a font which cannot be processed in order to avoid unnecessary transfer to the external device, while transfer without determination of the existence or non-existence of the font results in the increase of transfer traffic.SOLUTION: An image output system consists of a main body device and an external device which functions as an alternative device of the main body device and generates a page image by analyzing print data transferred from the main body device. The main body device comprises: resource management means for managing fonts; license management part for managing licenses of the fonts; and a job control part for determining whether or not print data is to be transferred on the basis of a prescribed determination reference when the font is not registered in the main body device but the license thereof is valid. |
