Tape printing device

The present invention aims to produce a label which has a size, margins and a character arrangement as a user desired, and aims to reduce a wasteful consumption of tape (T). In a tape printing device (5) of the present invention, there is established an enlargement printing mode in which a large pseudo label, whose width is wider than the width of tape, can be obtained when the tape (T) is divided into division portions in the longitudinal direction of the tape (T) and when the division portions are arranged in the direction of the width of the tape (T). When printing in this mode, the tape printing device (5) prints not only a character string but a marker which indicates the dividing positions in the longitudinal direction of the tape (T), with the intention of improving the quality of the pseudo label. Further, the tape printing device (5) of the present invention has the function of automatically setting the length of the front and rear margins according to the width of the tape (T) and the function of printing a square-array dot pattern on a wide region which is wider than the character string. Moreover, the tape printing device (5) of the present invention has the function of feeding the tape, for example, between a print head and a cutter, when instructing to stop printing the character string, without printing characters. Furthermore, the tape printing device of the present invention has the function of printing a character string even when accelerating and decelerating a tape feeding motor. Thus, desirable margins or the like can be realized and the reduction in wasteful consumption of the tape can be achieved by making use of theses functions. Additionally, the tape printing device of the present invention has the function of inputting, taking in and printing (1/M)-scale reduced numeric characters, each of which has a size that is (1/M) the size of a full-size character. Thus, the variety of the manners of printing numeric characters can be increased.
