Abstract
An impact printer in which a printing drum having a plurality of lines each containing different characters is associated with printing hammers. The printing hammers are driven into contact with the characters by a driving shaft having a driving projection thereon. The driving projection is separated into driving projection sections which are axially and radially displaced along the driving shaft. Each section will selectively engage different printing hammers so that all hammers will not operate at once for the same characters. The characters in the lines are also displaced angularly of the printing drum so that some of the characters in one line will be printed responsive to one driving projection and the other characters in the one line will be printed in response to the other driving projection section.
