US Patent 7315316 Printer

A printer includes a conveyance mechanism capable of conveying a long recording medium in a first direction from a supply unit storing therein the recording medium, toward an image recording unit capable of recording a color image on the recording medium, and in a second direction reverse to the first direction, with opposing the recording medium to the image recording unit. The conveyance mechanism is controlled to convey the recording medium in the first direction until a leading edge of the recording medium reaches a position distant in the first direction from the image recording unit, and then convey the recording medium in the second direction. The image recording unit is controlled to record frames of color images on the recording medium being conveyed in the second direction by the conveyance mechanism, and form a non-record region in which no image is recorded, on the recording medium between the leading edge and the last recorded color image.
