  • a scanner having a scanning area of a second size which is smaller than the first size, the scanner constituting means for scanning every portion of a whole area of the large document and for producing a scanning signal representative of the area thus scanned;

    a memory having a storage capacity for holding data representative of a document of a third size;

    a magnifier for adjusting by a magnification ratio a size of an image represented by the scanning signal to fit within the storage capacity of the memory, the magnification ratio being adjusted while taking into account not only the storage capacity of the memory but also the maximum size of the printer; and

    the printer, for printing a document of a fourth size by reproducing in eye-readable form the data held in the memory.
