Abstract
A novel rotary printing device, such as a daisy-type printwheel, for use in an impact printer, having identifying means thereon. In one form, plural protrusions, extending axially outwardly from the printing device, are provided and the angle between the protrusions serves the dual function of identifying the print element characteristics and identifying the reference position of the printing device for 'arming' the printer with the information. In another form, a single protrusion is provided solely for identifying the reference position. A method and apparatus for in situ identification of the novel rotary printing device also forms a part of the instant invention.
