ABSTRACT:
A printing apparatus includes N heating elements arranged in a line, and prints data on a label by each line by selectively supplying a current to these heating elements in accordance with printing data. The printing apparatus has a first memory for storing a plurality of line printing data constituting printing information including special information, a second memory for storing a plurality of line printing data constituting ordinary printing information, and a control unit which generates drive data corresponding to a logical sum of the one line printing data from the first memory and that from the second memory so as to cause the heating elements to be selectively energized during a first printing period of each line printing cycle. Drive data corresponding to the one line printing data from the first memory is generated so as to cause the heating elements to be selectively energized during a second printing period of each line printing cycle.
