<p>PURPOSE:To make it possible to print such that boundaries of printed parts are distinct by providing setting means for setting black at black both end positions of print data and white at other positions and input means for inputting the boundary data and the print data to a head between adjacent lines. CONSTITUTION:A 1 clock delay data made of an original data a is assumed to be a print data b and a data ORed and ANDed with the original data a, the 1 clock delay data b, and a 2 clocks delay data c is assumed to be a boundary data d. At first, an input means 1 inputs the print data b to a line thermal. head 2 so as to print by using a heating control means 3. Next, during the printing of the print data b by the heating control means 3, the boundary data d obtained at a setting means 4 constituted of D flip-flop circuits 5, 6, several OR circuits 7, 8, 9, and an AND circuit 10 is inputted to the line thermal head 2. After the printing of the print data b, the printing is carried out by the heating control means 3 before a paper proceeds to the next line.</p> |
