5. The printing apparatus according to claim 4 , wherein one of the protocols to be used by the printing function is used for transmitting, to the print service, a printer access token for authentication of the printing apparatus and an identifier for identification of a user authenticated by the authentication function, acquiring a list of print jobs associated with the user from among all print jobs stored in the real printer queue, and executing processing to acquire and print a print job selected from the list of print jobs associated with the user.

6. The printing apparatus according to claim 4 , wherein one of the protocols to be used by the printing function is used for transmitting, to the print service, a printer access token for authentication of the printing apparatus and a user access token, acquiring a list of print jobs associated with the user from among all print jobs stored in the virtual printer queue, and executing processing to acquire and print a print job selected from the list of print jobs associated with the user, the user access token being issued when the user is authenticated through input of user authentication information for authentication by the print service.

7. The printing apparatus according to claim 4 , wherein one of the protocols to be used by the printing function is used for transmitting, to the print service, a printer access token for authentication of the printing apparatus and a card identifier (ID) of an integrated circuit (IC) card used for utilization of the authentication function, acquiring a list of print jobs associated with the user from among all print jobs stored in the virtual printer queue, and executing processing to acquire and print a print job selected from the list of print jobs associated with the user.

8. The printing apparatus according to claim 4 , wherein one of the protocols to be used by the printing function is used for transmitting, to the print service, a printer access token for authentication of the printing apparatus and an identifier for identification of a user authenticated by the authentication function, acquiring a list of print jobs associated with the user from among all print jobs stored in the virtual printer queue, and executing processing to acquire and print a print job selected from the list of print jobs associated with the user.

9. A method of controlling a printing apparatus, the printing apparatus including a printing function and an authentication function, the printing function achieving cloud print by performing processing to register the printing apparatus on a print service connected via an Internet and processing to acquire a print job from a printer queue of the print service, the authentication function authenticating a user to limit use of a function, the method comprising:

acquiring, from the print service, information relating to a printer queue type associated with the registered printing apparatus, and acquiring, from the authentication function of the printing apparatus, information relating to whether to validate or invalidate the authentication function; and

determining one protocol from among a plurality of protocols used for acquisition and printing of the print job, based on at least two pieces of acquired information,

wherein the printer queue type includes at least a real printer queue, the real printer queue being used in a case where a printer object of the print service and the printing apparatus are associated in a one-to-one relationship, and

wherein one of the plurality of protocols to be used by the printing function is used for transmitting at least a printer access token for authentication of the printing apparatus to the print service, acquiring an information of print jobs stored in the real printer queue, and executing processing to acquire and print a print job selected from a list of print jobs.

10. A non-transitory computer-readable storage medium storing a program configured to be executed by one or more processors of a printing apparatus that includes a printing function and an authentication function, the printing function achieving cloud print by performing processing to register the printing apparatus on a print service connected via an Internet and processing to acquire a print job from a printer queue of the print service, the authentication function authenticating a user to limit use of a function, the program including instructions, which when executed by the one or more processors, cause the printing apparatus to perform operations comprising:

acquiring, from the print service, information relating to a printer queue type associated with the registered printing apparatus, and acquiring, from the authentication function of the printing apparatus, information relating to whether to validate or invalidate the authentication function; and
