Abstract
A label printer for printing labels can typically have a pressure roller and a corresponding print head, which print head can have a support, a spring base plate, and a spring disposed between the support and the spring base plate to bias the print head into engagement with the pressure roller. The spring base plate can be rotationally mounted on a bearing shaft which is preferably parallel to the pressure roller, and the free end of the bearing shaft can be flattened over a portion of its length to form two parallel key surfaces for engaging with a locking element that adjusts the biasing force of the spring by engaging and positioning the spring base plate. The locking element has a keyhole-like opening, with a circular portion having a diameter which is approximately equal to the diameter of the free end of the bearing shaft, and a narrow portion having a width approximately equal to the distance between the key surfaces of the bearing shaft to thereby non-rotationally fix the locking element to the bearing shaft.
