Abstract
In a miniature printer for printing with dots on printing paper, concentrically mounted driving cams provide both horizontal and vertical motions which synchronize the reciprocating action of the printing head mechanism with the paper feed and ink ribbon feed mechanism. Constant velocity linear motion is provided for the print head. The printing paper may be removed in either direction from the printer.
