Abstract: A tape printing apparatus compares a back-side background region of print data to be previously printed and a front-side background region of print data to be subsequently printed upon receipt of plural print data including background. If they are different, the tape printing apparatus creates a front-side color mixture tolerance region and a back-side color mixture tolerance region based on the front-side background region and the back-side background region, respectively, so that the front-side color mixture tolerance region and the back-side color mixture tolerance region are arranged continuously. The apparatus sets cut positions at a front edge border and a back edge border of each print data and cut the tape off at those portions while carrying out full-color print on the tape based on respective print data.
