Abstract: In a printer, an accommodating portion accommodates printing agent supplied from a first cartridge. A print execution device prints with the printing agent supplied from the accommodating portion. A processor acquires first information concerning a residual quantity of the printing agent remaining in the first cartridge. The processor acquires second information concerning a preparation of a second cartridge to be replaced with the first cartridge. If the residual quantity is below a reference quantity and if the second information is acquired, the processor allows the print execution device to perform printing under a cartridge removed state where the first cartridge is removed from the mount portion. If the residual quantity is larger than or equal to the reference quantity or if the second information is not acquired, the processor prohibits the print execution device from printing under the cartridge removed state.

Abstract: There is provided a function execution apparatus which, when a wireless connection request is received from a specific device in a specific state where wireless connections are established between the function execution apparatus and N devices which are an upper limit number of devices, transmits an inquiry signal to each of K devices among the N devices to inquire whether each device which is a final transmission destination of the inquiry signal activates a specific application program for causing the function execution apparatus to execute a specific function; select a target device, for which the wireless connection is to be disconnected, among the K devices based on a result of the inquiry; disconnect a wireless connection with the target device; and establish a wireless connection with the specific device after the wireless connection with the target device is disconnected.

Abstract: A management device may be connected with a specific device via a network, and cause the specific device to update a plurality of programs.

Abstract: A communication apparatus may include a reception portion, a decision portion, and a transmission portion. The reception portion may receive a first data request transmitted through a first security level communication, and a second data request transmitted through a second security level communication, the second security level being more secure than the first security level. The decision portion may decide whether a specific data request is the first data request or the second data request. The transmission portion may transmit a specific data to an apparatus that is a transmission source of the specific data request if the specific data request is the second data request, and may transmit different data to the apparatus if the specific data request is the first data request. The different data contains display information for causing the apparatus to retransmit the specific data request through the second security level communication.

Abstract: A printer may judge whether a first type of communication with the print mediation server. The printer may execute the first type of communication and receive a predetermined notification in a case where it is judged that the first type of communication is executable. The printer may, (A) execute, when the predetermined notification is received a second type of communication so as to acquire specific address information, in the case where being judged that the first type of communication is executable and (B) execute, even if the predetermined notification is not received, the second type of communication at a predetermined timing so as to acquire the specific address information in a case where it is judged that the first type of communication is not executable. The printer may acquire the specific print data and print an image represented by the specific print data.
