High technology reports which require technical symbols and scholarly documents which use more than one language are two instances where the number of font on a standard single print wheel typewriter are insufficient. The three element print wheel configuration shown greatly increases the number of font available. The print wheels 1, 2 and 3 have different character sets and are grouped around a single non~moving type hammer with a 120° phase angle between the print wheels. A slight shift of the three element configuration in direction A would cause the characters of print wheel I to move into alignment with the hammer, and a slight shift in directions B and C would cause the characters of print wheels 2 and 3, respectively, to move into alignment with the hammer. A guide mechanism would provide the proper lateral spacing between print wheels.
