Communication apparatus and printer for performing wireless communication of image data representing image of print target

A communication apparatus comprising:

• a first wireless communication interface;
• a second wireless communication interface which is different from the first wireless communication interface;
• a display unit;
• a processor;
• and
• a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the communication apparatus to perform:
• communicating a wireless setting value with a printer via the first wireless communication interface;
• establishing a wireless connection with the printer via the second wireless communication interface using the wireless setting value that has been communicated with the printer via the first wireless communication interface;
• sending first image data representing a first image of a print target to the printer via the second wireless communication interface using the wireless connection that has been established using the wireless setting value that had been communicated with the printer via the first wireless communication interface;
• receiving, after the first image data is sent to the printer via the second wireless communication interface using the wireless connection that has been established using the wireless setting value that had been communicated with the printer via the first wireless communication interface, a print completion notification from the printer via the second wireless communication interface using the wireless connection that has been established using the wireless setting value that has been communicated with the printer via the first wireless communication interface, the print completion notification indicating that a print of the first image is completed by the printer, and the print completion notification being sent from the printer after the print of the first image has been completed by the printer;
• controlling, after the first image data is sent to the printer via the second wireless communication interface using the wireless connection that has been established using the wireless setting value that had been communicated with the printer via the first wireless communication interface, the display unit to display an instruction screen for receiving a user instruction as to whether the wireless connection via the second wireless communication interface is to be disconnected;
• and
• disconnecting the wireless connection without sending a disconnect signal for disconnecting the wireless connection established between the communication apparatus and the printer from the communication apparatus to the printer in a case where the processor determines that the print completion notification is received from the printer and an instruction is received in the instruction screen that the wireless connection with the printer via the second wireless communication interface is to be disconnected, the wireless connection has been established using the wireless setting value that had been communicated with the printer via the first wireless communication interface, the wireless connection being disconnected due to the communication apparatus transiting from a state of sending a response signal to an existence confirmation signal received from the printer to a state of not sending the response signal.

A printer comprising:

• a first wireless communication interface;
• a second wireless communication interface which is different from the first wireless communication interface;
• a print performing unit;
• a processor;
• and
• a memory storing computer-readable instructions therein, wherein
• the first wireless communication interface communicates a first wireless setting value with a communication apparatus, and
• the computer-readable instructions, when executed by the processor, cause the printer to perform:
• establishing a wireless connection with the communication apparatus via the second wireless communication interface using the first wireless setting value that has been communicated with the communication apparatus via the first wireless communication interface;
• receiving first image data from the communication apparatus via the second wireless communication interface using the wireless connection that has been established using the first wireless setting value that had been communicated with the communication apparatus via the first wireless communication interface;
• controlling the print performing unit to perform a print of a first image represented by the first image data;
• and
• sending a print completion notification to the communication apparatus via the second wireless communication interface using the wireless connection that has been established using the first wireless setting value that had been communicated with the communication apparatus via the first wireless communication interface after the print of the first image is completed, the print completion notification indicating that a print of the first image is completed,
• wherein the wireless connection is disconnected without sending a disconnect signal for disconnecting the wireless connection established between the communication apparatus and the printer from the communication apparatus to the printer in a case where the print completion notification is sent to the communication apparatus and an instruction is received in the communication apparatus that the wireless connection with the communication apparatus via the second wireless communication interface is to be disconnected, the wireless connection has been established using the first wireless setting value that had been communicated with the communication apparatus via the first wireless communication interface, the wireless connection being disconnected due to the communication apparatus transiting from a state of sending a response signal to an existence confirmation signal received from the printer to a state of not sending the response signal.
