摘要：
A method of expanding the function of an application in a computer that operates under an operating system and executes specific processes by an application has a step that acquires and sends print data that is output from the application to a driver to a communication port before the print data is received by the driver; a step that acquires and relays the transmitted print data, or the print data that is output from the application to the communication port, before the print data is received by the communication port; and a step that expands the function of the relayed print data on the application layer, and outputs the processed data to a communication port.
