A printing pressure damping mechanism for use with a hand labeler: a hand lever is pivotally connected to the frame of the hand labeler. A printing head is carried by the hand lever so that it may move toward a printing platen when the hand lever is squeezed. An auxiliary lever is spaced from the hand lever and is movable to and from the hand lever. A shock absorbing coil spring is interposed under compression between the hand lever and the auxiliary lever so as to bias the levers apart. The auxiliary lever further moves against the biasing force of the coil spring when the printing head abuts the platen, so that the squeezing force which might otherwise be applied as a printing force by the printing head to the platen can be damped to a preset lever through the spring biased cooperation of the two levers. The platen is also spring biased to damp printing pressure.
