Control method and information processing apparatus for displaying information related to a function

An information processing apparatus on which an expansion application configured to expand a function of print data generation software runs, the information processing apparatus comprising at least one processor operating to:

• obtain attribute data on a printing apparatus, the attribute data being output from the printing apparatus;
• obtain data indicating a print function;
• determine whether or not information indicating a specific function is included in the obtained data indicating the print function;
• add information related to the specific function based on attribute information included in the obtained attribute data if information indicating the specific function is determined not to be included in the obtained data;
• and
• display a setting screen including a setting item of the specific function based on the added information related to the specific function,
• wherein if a user designates the setting item of the specific function which is determined not to be included in the obtained data, perform processing for generating print data based on the specific function,
• wherein the print data generation software is an Internet Printing Protocol (IPP) driver, and the print data is data in a format according to IPP, and
• wherein the information related to the specific function is added based on the attribute information and a same setting item is thereby displayed as the setting item of the specific function regardless of whether the attribute information indicates a standard attribute of the IPP or an originally-defined attribute.
