摘要

A form for printing print data, such as business data generated by an application program is generated by a form defining program. The form defining program designates a specific item (specific data item) in the form based on the predesignated print color of the form. A data discriminating section extracts data in a specific data item from the print data supplied from the application program. In accordance with the contents of the data in the specific data item, a color control command for changing the predesignated color of the form is generated. A printer controller change the color of the form in accordance with the color control command, supplied via a printer driver, and outputs the resultant data to a printing section. The printing section prints the print data in the color-changed form.
