A method of reading a two-dimensional code carried on an article in the form of an array of dots that represent image processing instructions includes the step of scanning the article with a scanner of an image processing device to generate a number of pixels represented by each dot. A signal representing a pixel pattern to be communicated to processing circuitry of the image processing device is generated. The signal is processed at the processing circuitry to determine an extent of area on the article covered by the two dimensional code. The signal is processed to detect a bit pattern represented by the pixel pattern. The bit pattern is written as bytes to a data storage means of the image processing device. The resultant byte pattern is processed. |
