Recording apparatus, recording method, and storage medium

A recording apparatus (1), which uses an ink sheet (8) having ink of plural colors coated sequentially thereon and transferring ink to a recording medium (Pl) for recording in accordance with image data, is capable of recording on a plurality of recording media having different sizes, at the same time, being capable of using selectively plural ink sheets each corresponding to each of the plural recording media of different sizes. This recording apparatus comprises means (16) for detecting the size of a recording medium to detect the size of the recording medium to be used for recording; means for detecting the size of an ink sheet to detect the size of a recording medium corresponding to the ink sheet to be used for recording; and controlling means to control the recording operation in accordance with the size of the detected recording medium and the size of the recording medium corresponding to the detected ink sheet. With these means thus arranged, it is made possible to record without recording improperly any smaller images that may be unfit for the size of the recording sheet or staining the platen and others in the interior of the apparatus even when the recording medium and the ink sheet installed thereon are different in its sizes or the user does not designate the size of the recording medium to be used.
