Abstract
A printing apparatus is provided with a thermal head which has a plurality of heatable elements disposed in a line and divided into plural groups. A control unit controls the plural groups of heatable elements in accordance with printing data to generate heat to thermal-transfer ink of an ink ribbon onto a label tape, thereby printing the printing data on the label tape. A boundary heatable element within one group of heatable elements which is disposed adjacently to other group of heatable elements is driven in accordance with the printing data when the other group of heatable elements are driven to generate heat. The boundary heatable element generates heat twice to prints data twice on the label tape at a portion corresponding to the boundary between two groups of heatable elements, there by printing data on the portion with higher printing intensity. Further, while controlling the thermal head to generate heat, the control unit controls a stepping motor to advance the label tape in synchronism with heat generation by the thermal head, wherein the printing data are printed in elliptical patterns in a tape running direction.
