The number of dots is calculated by nL + nH ! 256. • If the bit-image data input exceeds the number of dots to be printed on a line, the excess data is ignored. • d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not print a dot. • If the values of m and nH are out of the specified range, the following data is processed as normal data. • After printing a bit image, the printer returns to normal data processing mode. • In page mode, double density bit image data is not available. • The relationship between the image data and the dots to be printed is shown on the next page.
