A mosaic printing head for typewriters, data printers, teleprinters and the like, utilizing dot-producing pin-like printing elements for recording characters in the form of a dot pattern upon a data carrier, employing a plurality of dot forming elements, each of which is adapted to be actuated by an elongated, piezoelectric transducer which is subjected to electric fields in rapid succession to effect changes in the length of each transducer and thereby produce driving forces upon the associated element.
