Display of two functions of device used with data processing apparatus

A data processing apparatus comprising:

• a storage;
• an input interface;
• a communication interface;
• and
• a control device configured to perform:
• receiving a first selection of a first function between the first function and a second function through the input interface;
• searching for at least one device communicable through the communication interface;
• receiving, through the input interface, a selection of a first device for executing the first function among the at least one device identified in the searching;
• determining whether the first device is capable of executing the second function which is different from the first function selected in the first selection;
• storing identification data of the selected first device in the storage;
• after storing the identification data of the first device, receiving a second selection of the second function through the input interface;
• in a case where the selected first device is determined to be capable of executing the second function, which is different from the first function selected by the first selection, and the second selection of the second function is received, displaying the stored identification data of the first device on the display in a manner indicating that the first device executes the second function;
• and
• in a case where the selected first device is determined to be incapable of executing the second function, which is different from the first function selected by the first selection, and the second selection of the second function is received, avoiding displaying the stored identification data of the first device on the display in the manner indicating that the first device executes the second function.

A non-transitory computer-readable storage medium storing a set of program instructions installed on and executed by a computer of a data processing apparatus for controlling a device having a printer function and a scanner function, the data processing apparatus including a communication interface, an input interface, a storage, and a display, the set of program instructions, when executed, causing the data processing apparatus to perform:

• receiving a first selection of the printer function through the input interface;
• searching for at least one device communicable through the communication interface;
• receiving, through the input interface, a selection of a first device for executing the printer function among the at least one device identified in the searching;
• determining whether the first device is capable of executing the scanner function;
• storing identification data of the selected first device in the storage;
• after storing the identification data of the first device, receiving a second selection of the scanner function through the input interface;
• in a case where the selected first device is determined to have the scanner function, and the second selection of the scanner function is received, displaying the stored identification data of the first device on the display in a manner indicating that the first device executes the scanner function;
• and
• in a case where the selected first device is determined to not have the scanner function, and the second selection of the scanner function is received, avoiding displaying the stored identification data of the first device on the display in the manner indicating that the first device executes the scanner function.
