Abstract
In a high-speed digital printing apparatus having duplex capability, second-side images must be rotated. In order to quickly rotate the second-side images, the image data for the images are read out from memory in a reverse order of addresses, with each address corresponding to one byte. As each byte is transferred to an imager, a relationship of sets of bits, each set of bits corresponding to one pixel, are altered within each byte.
