Abstract:
1. A tape printing apparatus for printing a print image by each dot line onto a tape by driving a plurality of heating elements of a print head, the heating elements being aligned corresponding to the dot lines of the print image where dots are arrayed in a width direction of the tape, while moving the tape in a longitudinal direction thereof relative to the print head, the tape printing apparatus comprising: dot line analyzing means for analyzing each of the dot lines of the print image made up of a mixture of print lines which are the dot lines including the dots to be printed and blank lines which are the dot lines including no dots to be printed, whereby each of the dot lines is analyzed to be the print line or the blank line, thereby obtaining a line analysis result; means for detecting, based on the line analysis result, a duration of the consecutive blank lines when printing is not consecutively performed while the tape is moved, due to the consecutive blank lines on the tape in a longitudinal direction thereof; applied energy adjusting means for adjusting the energy applied to the print head in printing each of the print lines, based on the duration of the consecutive blank lines and the number of the consecutive print lines from the line analysis result.
