ABSTRACT OF THE DISCLOSURE A constant pressure printing mechanism for a portable label printing machine, or the like, comprising a driving member which is disposed on either the movable hand lever or the stationary hand grip of the label printing machine and a pressure receiving member which is disposed on the other of the hand lever or the hand grip. The invention uses stored energy derived from a manual squeezing operation to produce the printing stroke, independently of the intensity and duration of a manual squeeze. In one form, the driving member comprises a movable roller, a guiding means to allow the movable roller to move therethrough and an elastic means which always urges the movable roller in one direction and the pressure receiving member comprises a contact surface and an arcuate surface to be brought into contact with the above movable member when the hand lever is squeezed. In another form, the driving member is provided with a spring-actuated projection member and the pressure receiving member is provided with a contact surface and an engaging recess, which are brought into engagement with the projection member.
