CONSTITUTION:When one line of the line containing the rule of document data is printed, a column equivalent address table and a color information table are obtained by the text-development of a character string (its color attribute is red). Besides, by developing rule data, the column equivalent address table of the rule is obtained. At the same time, when blue is set as the color of the rule, its color information table is prepared. Then, the logical sum of the character and the color information table of the rule is obtained to be combined with the above-mentioned color information table and a column equivalent color map is prepared. Each column of this map is developed as the color information of 12 dots. At the same time, when 4 dots are given as a character interval, the same color information as the next left color information is set as 4 dot and a dot unit color map is obtained. Thereby, dot data are obtained. Therefore, because the color of the rule can be set for each one line as a printing operation unit, the color indication of each rule is not required and the operating efficiency in color printing is improved.
