Communication Apparatus

A terminal device comprising:

• an interface;
• and
• a control device configured to:
• receive a specific signal from a printer comprising a printing execution unit via the interface, the specific signal including identification information;
• determine whether an inter-device distance between the terminal device and the printer is equal to or smaller than a first predetermined distance by using a first reception radio wave intensity of the received specific signal;
• perform a first process by using the identification information included in the specific signal received from the printer when it is determined that the inter-device distance is equal to or smaller than the first predetermined distance, such that printing data is supplied from a server to the printer;
• again receive the specific signal from the printer via the interface after performing the first process;
• determine whether the inter-device distance is equal to or smaller than a second predetermined distance by using a second reception radio wave intensity of the again-received specific signal, the second predetermined distance being smaller than the first predetermined distance;
• and
• perform a second process by using the identification information included in the again-received specific signal received from the printer when it is determined that the inter-device distance is equal to or smaller than the second predetermined distance such that the printing execution unit of the printer executes printing in accordance with the printing data, which has been obtained from the server by the printer.
