The present invention relates to a character information printing apparatus for printing a previously inputted character string on a print medium in which at least a transversal dimension is fixed. The apparatus is adapted to introduce instruction information as to a special printing in which, when X print medium portions on which printings are completed are arranged contiguously in the longitudinal and transversal directions thereof, one quasi print resultant having a dimension X times that of each of the print medium portions is obtained. The apparatus includes special printing introducing means for introducing either an operation of performing printing on all the X print medium portions or an operation of performing printing on a part of the print medium portions located in a position specified in the print resultant; print attribute determining means for determining a print attribute, such as character position, with respect to each of the print medium portions; and printing means for printing, when the instruction of performing printing on a part of the print medium portions located in the position thus specified, a character string portion corresponding to the specified position on a print medium in accordance with the print attribute thus determined.
