Method of setting option when function is performed by using shortcut, and image forming apparatus to perform the method

A method comprising:

• receiving an input selectively designating a set option in an option setting page displayed on a user interface of an image forming apparatus as a variable option for at least one shortcut;
• receiving an input selecting a shortcut from the one or more shortcuts, each of the one or more shortcuts set to correspond to a function of the image forming apparatus;
• and
• selectively displaying the option setting page when the shortcut is selected, such that:
• if an option necessary to perform the function corresponding to the selected shortcut exists and is not set, displaying the option setting page to set the option necessary to perform the function corresponding to the selected shortcut,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, and if the set option is not designated as the variable option, performing the function corresponding to the selected shortcut without displaying the option setting page according to the set option,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, and if the set option is designated as the variable option and the input selecting the shortcut is received for a duration of time less than a predetermined duration of time, performing the function corresponding to the selected shortcut according to the set option without displaying the option setting page,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, and if the set option is designated as the variable option and the input selecting the shortcut is received for a duration of time equal to or greater than the predetermined duration of time, displaying the option setting page to change the variable option, and
• if the option necessary to perform the function corresponding to the selected shortcut does not exist, performing the function corresponding to the selected shortcut without displaying the option setting page.

An image forming apparatus, comprising:

• a user interface to provide a shortcut region with a plurality of selectable shortcuts each to correspond with a function of the image forming apparatus, and to receive an input to selectively designate a set option in an option setting page displayed on the user interface as a variable option for at least one shortcut;
• a job executer to execute a function corresponding to a selected shortcut;
• and
• a controller to, when the shortcut is selected, determine whether an option necessary to perform the function corresponding to a selected shortcut exists, and to selectively control the user interface to display the option setting page to set the option necessary to perform the function corresponding to the selected shortcut or control the job executer to perform the function corresponding to the selected shortcut without displaying the option setting page, based on the determination whether the option necessary to perform the function corresponding to the selected shortcut exists and based on whether the option necessary to perform the function corresponding to the selected shortcut is set if the option necessary to perform the function corresponding to the selected shortcut exists, such that
• if the option necessary to perform the function corresponding to the selected shortcut exists and is not set, the controller is to control the user interface to display the option setting page to set the option necessary to perform the function corresponding to the selected shortcut,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, the controller is to control the job executer to perform the function corresponding to the selected shortcut according to the set option without displaying the option setting page if the set option is not designated as the variable option,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, the controller is to control the job executer to perform the function corresponding to the selected shortcut according to the set option without displaying the option setting page if the set option is designated as the variable option and the input to select the shortcut is received for a duration of time less than a predetermined duration of time,
• if the option necessary to perform the function corresponding to the selected shortcut exists and is set, the controller is to control the user interface to display the option setting page to change the variable option if the set option is designated as the variable option and the input to select the shortcut is received for a duration of time equal to or greater than the predetermined duration of time, and
• if the option necessary to perform the function corresponding to the selected shortcut does not exist, the controller is to control the job executer to perform the function corresponding to the selected shortcut without displaying the option setting page.
