ABSTRACT:
A serial printer for recording with a recording head while synchronizing with a movement of a carriage reciprocated on an apparatus body and on which the recording head is mounted. A position of a linear encoder is detected by a detecting portion. A detecting signal from this detecting portion is compared with a reference voltage, and a pulse output as a synchronous signal is generated. A duty of this pulse output is adjusted to obtain a well-recorded result.
