Abstract
In a thermal printer having a platen and thermal print head, the print head is supported on a special print head support structure which allows the print head to pivot so as to apply a uniform pressure across the width of labels or price tags which are fed between the print head and the platen. The support structure for the print head includes: a two-part support member including a print head attachment member for holding the thermal print head and a pressing member for pressing the thermal print head toward the platen; a fixed spindle for rotatably supporting the support member; and a pivot member between the thermal print head attachment member and the spindle, the pivot member enabling the attachment member, and therefore the print head, to pivot in a plane parallel to the axis of the platen in a manner which tends to equalize the pressure across the labels or price tags being imprinted.
