In the conventional printing apparatuses wherein a type-wheel and a carriage are driven respectively by stepping motors, after turning on power supply, a original position of the carriage is initialized by a sensor method, and a original position of the type-wheel is initialized by a step-out method. In this case, a sensor is required to be mounted within a very narrow range equivalent to several steps, and a stopper for restraining rotation of the type-wheel is required to be mounted within a very narrow range in the vicinity of a frame side wall. Disclosed are a printing apparatus with a type-wheel and an initializing method of the printing apparatus wherein the carriage is restrained at the frame side wall part, the original position of the carriage is initialized by the step-out method, and after the carriage has been moved to a predetermined position near the printable range, then the reference positions of the type-wheel and the driving means thereof are agreed each other, and the carriage is moved to the vicinity of the frame side wall part, and the original position of the type-wheel is initialized by the step-out method.
