A non-transitory computer-readable recording medium storing computer-readable instructions which causes an information processing terminal to transmit first request information requesting an image processing apparatus to transmit first information, receive the first information, as a response to the first request information, from the image processing apparatus, determine whether a set value of the received first information is the first value or the second value. When the first information is set to the first value, the instructions further cause the information processing terminal to transmit second request information requesting the image processing apparatus to transmit the second information, and receive the second information, as a response to the second request information, from the image processing apparatus. When the first information is set to the second value, the instructions do not cause the information processing terminal to transmit the second request information and to receive the second information.
