A hand operated marking device includes a pair of housings movably interconnected together, a first one of the housings adapted to be received in a second one of the housings responsive to a compression of the housings; a printer located along a bottom surface of the first housing, the printer including a movable printhead exposed through an aperture of the first housing; a moving mechanism housed within at least one of the housings, the moving mechanism for moving the printhead in a printing direction responsive to the compression of the housings; and a shutter for covering the aperture of the first housing, the shutter adapted to be retracted as the moving mechanism moves the printhead. The moving mechanism includes a pair of arms pivotally mounted at one end to the second housing and at the other end to the printhead, and further comprising an extension return spring extending between the other end of the arms and the first housing.
