A first communication apparatus including a control device configured to: receive a specific signal from a second communication apparatus; determine whether an inter-device distance between the communication apparatuses is equal to or smaller than a first distance; cause a server to supply printing data to a printer when the inter-device distance is equal to or smaller than the first distance; again receive the specific signal from the second communication apparatus; determine whether the inter-device distance is equal to or smaller than a second distance that is smaller than the first distance by using a second reception radio wave intensity of the again-received specific signal; and cause the printing execution unit to execute printing in accordance with the printing data when it is determined that the inter-device distance is equal to or smaller than the second distance.
