A medium stores computer executable programs. The programs cause an information processing apparatus being capable of data communication with an image recording apparatus to perform: generating image data of an image to be recorded; in a case of receiving manual double-sided printing instruction based on the generated image data, transmitting first image data of an image to be recorded on a first surface of a recording medium, together with a recording instruction based on the first image data and identification information to the image recording apparatus; and transmitting second image data of an image to be recorded on a second surface opposite to the first surface of the recording medium, together with a recording instruction based on the second image data and the same identification information as that transmitted with the first image data to the image recording apparatus, after transmitting the first image data.
