Abstract
An information processing apparatus has a printer driver and a device service associated with the printer driver as an output port of a print job generated by the printer driver. The printer driver receives data in accordance with a print instruction from an application operating on the information processing apparatus, generates a print job based on the received data, and outputs the print job to the output port. The print job is sent to the device service by an operating system using internal loopback. The device service connects to a print apparatus via a port that is different from the output port of the information processing apparatus, receives the print job from the printer driver, transmits a first control command for obtaining status information to the print apparatus, obtains the status information of the apparatus, and accepts print data received through a receiving port.
