A thermal printer has a fuser roller and a heating element movable relative to the roller between a nonfusing position and a fusing position. At the nonfusing position, the heating element is spaced a first preselected distance from the roller, and at the fusing position, the heating element is spaced a second preselected distance from the roller with the first distance being greater than the second distance. A protective web traverses a path between the heating element and the roller and covers a portion of the roller surface greater than the width of the heating element to thereby protect the roller surface.
