Abstract
PURPOSE: To minimize the time for travelling of a printing head by providing a means for processing informations on the current position of the printing head, the starting position of printing and the number of printed characters for every line.
CONSTITUTION: The informations from counters 12, 13 and 14 indicating respectively the current position Pp of a printing head 2, the starting position Ps of printing and the number n of printed characters, the latter two of which are given from the outside for every line, are outputted to an operating register. Now, when the relations among these informations are such, for instance, as expressed in the formula: (n-1)/2<Pp-Ps<n-1, i.e. when the printing head 2 is found between the starting position of printing and the ending position thereof and on the side of the ending position, a signal 16 for the stop position, a signal 17 for designating the direction of the level "1" (the right direction) and a signal 18 for designating the printing of the level "0" (designating non-printing) are outputted, thereby the printing head moving to the right and stopping. Next, the printing head, performing printing operation, moves to the left and stops at the position of (Ps-1) after performing the printing of n characters.
