Information processing apparatus, method of controlling the same, print system and storage medium

A method of controlling an information processing apparatus having a printer driver and a device service being associated with the printer driver as an output port of a print job generated by the printer driver, the method comprising:

• (a) receiving, in the printer driver, data generated in accordance with a print instruction from an application operating on the information processing apparatus, generating, in the printer driver, a print job based on the received data, and outputting, from the printer driver, the print job to the output port, wherein the print job is sent to the device service by an operating system (OS);
• (b) connecting the device service to a print apparatus via a port that is different from the output port of the information processing apparatus;
• (c) receiving the print job from the printer driver;
• (d) transmitting, from the device service to the print apparatus, a first control command for obtaining status information of the print apparatus;
• (e) obtaining, by the device service, the status information of the print apparatus in accordance with having received a response to the first control command from the print apparatus, and transmitting the print job based on the status information of the print apparatus;
• and
• (f) accepting, by the device service, print data received through a receiving port,
• wherein the OS sends the print job to the receiving port using internal loopback.

A non-transitory computer-readable storage medium storing a program for causing a processor to execute a method of controlling an information processing apparatus having a printer driver and a device service being associated with the printer driver as an output port of a print job generated by the printer driver, the method comprising:

• (a) receiving, in the printer driver, data generated in accordance with a print instruction from an application operating on the information processing apparatus, generating, in the printer driver, a print job based on the received data, and outputting, from the printer driver, the print job to the output port, wherein the print job is sent to the device service by an operating system (OS);
• (b) connecting the device service to a print apparatus via a port that is different from the output port of the information processing apparatus;
• (c) receiving the print job from the printer driver;
• (d) transmitting, from the device service to the print apparatus, a first control command for obtaining status information of the print apparatus;
• (e) obtaining, by the device service, the status information of the print apparatus in accordance with having received a response to the first control command from the print apparatus, and transmitting the print job based on the status information of the print apparatus;
• and
• (f) accepting, by the device service, print data received through a receiving port,
• wherein the OS sends the print job to the receiving port using internal loopback.
