装置。[Claim for Utility Model Registration] A hammer bank that holds a plurality of dot printing hammers at predetermined intervals along the printing line is moved back and forth along the printing line, and the dots are printed in the process of this reciprocating movement. In a line printer, a paper feeding means consisting of a pair of rollers provided on both sides of the hammer bank in the paper running direction, and at least four sheets of paper provided on both sides of the paper feeding means in the paper running direction to detect the presence or absence of paper. Presence detection means and paper presence detection means receive outputs, and if one detection means detects that there is no paper, printing during the reciprocating movement of the hammer bank is stopped and printing is performed only during outward or return movement. 1. A control device for a dot line printer, comprising control means for generating a print control command and generating a print end signal when two detecting means detect that there is no paper.
