Terminal Device

A non-transitory computer-readable medium having instructions to control a printer to perform operations, operations comprising.

• receiving a print target data to be printed from a terminal device;
• starting, in response to the receiving the print target data, to repeatedly transmit a signal to calculate a distance between the printer and the terminal device;
• receiving, when the calculated distance between the printer and the terminal device that receives the signal is equal to or less than a predetermined distance, a start instruction causing to start a print according to the print target data, from the terminal device which is located within the predetermined distance;
• and
• executing, in response to the receiving the start instruction, the print according to the print target data.

A printer comprising:

• a controller,
• wherein the controller controls the printer to perform:
• receiving a print target data to be printed from a terminal device;
• starting, in response to receiving the print target data, to repeatedly transmit a signal to calculate a distance between the printer and the terminal device;
• receiving, when the calculated distance between the printer and the terminal device that receives the signal is equal to or less than a predetermined distance, a specific instruction from the terminal device, the specific instruction causing the printer to start a print according to the print target data;
• and
• executing, in response to receiving the specific instruction, the print according to the print target data.
