ABSTRACT:
A serial printer of the type employing a petal like print thimble is improved by employing a first motor for character selection in a circumferential direction of the thimble, and a second motor for selection of the vertical position of the print thimble, which has plural circumferentially arrayed sets of characters spaced vertically, by shifting the shaft of the first motor along its axis. When the second motor rotates in a second direction, it serves to advance the ink ribbon of the printer.
