Daisy wheel printers employ traditional daisy wheels, as shown in the figure, wherein fingers 10 extending from central hub portion 11 contain the characters 12 to be printed. In mounting these print wheels on the drive shaft, it is desirable to obtain automatic coupling with the shaft without the need for any manual intervention by the operator. Present print wheel structure provides for such a simple coupling. This coupling eliminates any misregistration which might occur between the daisy print wheel and impact printer hammers due to a floppy coupling between the print wheel and the drive shaft.
