  • Apparatus and method for printing validated image data in a noisy environment
    Patent number: 7688476
    Abstract: A method and apparatus for transmitting and receiving image data and control characters across an interface that is subject to noise for output to a printer. The image data and the control characters are transmitted across the interface to a receiver device. A determination is made as to whether or not a line of image data has been sufficiently transferred to the receiver device and, if the current line of image data has not been sufficiently transferred, there is provided for output to the printer a prior sufficiently received line of image data in replacement of the current line of image data so that the prior line of image data is printed at least twice in succession.
