An information processing apparatus executes an operating system (OS) including a printing system that supports a first search protocol, and a printing function to generate a print job conforming to a first printing method and send the generated print job to a printer as a standard. A memory stores instructions, and a processor executes the instructions causing the information processing apparatus to receive a message conforming to the first search protocol from another printer that has been newly detected via the first search protocol if instructions for the use of the printing system included in the OS are provided by a user, and activate, upon condition that the detected printer has been selected and is determined not to conform to the first printing method based on contents of the received message, a function for downloading a print plug-in that supports the detected printer, wherein the print plug-in generates another print job and sends the generated another print job to the detected printer.
