Abstract
A serial printer includes a control circuit for driving the printer carriage. The control circuit detects the change of level of a home position signal in synchronism with a print position signal which is produced based upon occurrence of particular data selected out of a cycle of data for driving a step motor so as to increase the permissible range of variation in the change of the level of the home position signal that takes place due to mechanical vibrations differing in mode or phase.
