TAPE PRINTING APPARATUS

In a tape printing apparatus capable of printing character strings over a plurality of lines on a tapelike printing medium, printing, in which print positions of input lines are reversed or interchanged, can be easily performed. In printing input character strings over a plurality of lines, print data of each line is unfolded by an amount corresponding to one line of a thermal head 15 (S13, S14). When unfolding of data of all lines is completed (S15), data of each line is rearranged in a line buffer 50 according to a line-corresponding table. A print result in which the print positions are reversed or interchanged can be obtained by printing information in the line buffer.
