<p>PURPOSE:To achieve the lowering of noise by reducing release sound generated by the sticking of a thermal head and recording paper, by applying a heating pulse to a heat generating element before recording paper is moved to the next line when paper feed was interrupted for a predetermined time or more after recording operation. CONSTITUTION:One line is recorded in a time sharing system and the sub- scanning of recording paper is performed by the interval (l) of one line. When the paper feed sub-scanning operation was interrupted for a set time or more, a pulse is outputted from a timer circuit at time t3 after a set time was elapsed from time t2. By the timing of this pulse, the recording information of the line immediately before interruption is again written in a lapped state. In this case, the thermal layer of the recording paper may be heated almost up to the vicinity of m.p. Therefore, this setting may be performed by applying a heating pulse to a part of the heat generating element participated in recording operation. Or, this setting is achieved by making voltage lower than that of the heating pulse when usual printing operation is performed or shortening the width of the heating pulse. Next, the recording of the next line and paper feed operation are rapidly repeated after the completion of lap-writing.</p> |
