Abstract
An apparatus for outputting image data to a printer that includes a generator, a determining device, a compression device, a storage controller and a transfer device. The generator generates the image data and the determining device determines whether or not a band or a page of the image data generated by the generator is to be compressed, on the basis of an amount of the generated image data to be transferred to the printer. The compression device compresses the image data generated by the generator into compressed data by a band unit or a page unit, in accordance with a determination from the determining device. The storage controller, if the determining device determines that the band or page of the generated image data is to be compressed, controls a memory to store the band or page of the generated image data compressed by the compression device, and, if the determining device determines that the band or page of the generated image data is not to be compressed, controls the memory to store the band or page of the generated image data without compression. The transfer device transfers the stored data from the memory to the printer.
