Abstract
There is a printer comprising: a type wheel having a plurality of types; a type selecting apparatus for making the type wheel operative and thereby to lead the type selected from those types to a printing position; a signal generator to generate a striking signal to a printing hammer for making this selected type toward a printing paper; and a signal generator to generate a carriage moving signal to move a carriage on which the type wheel, type selecting apparatus and printing hammer are mounted. In this printer, the time intervals from the time of generation of the hammer driving signal until the time of generation of the carriage moving signal and until the time of generation of a wheel rotating signal are respectively changed with respect to the area of the individual type of the plurality of types. The time interval from the time of generation of the striking signal until the time of generation of the carriage moving signal is set on the basis of the time interval of generation of the striking signal which is set with regard to the individual type area.
