Abstract
A thermal printer for printing on a thermal print paper including a platen element of a porous material, a fibrous material or a plastic material having an inrregular surface is provided. The platen element is opposed to the printer heating element which generates thermal energy for printing on the thermal paper. The platen element is mounted in a pair of grooves in a holding member substantially parallel to the printing direction of the heating element and retained therein by an adhesive or compressive retaining members. The inlet and outlet edges of the platen element are rounded for facilitating paper transport thereby. The elasticity and deformity of the platen element permits intimate contact between the thermal head and the thermal paper for clearer printing with a smaller power input. Repetitive heating and cooling does not result in thermal stresses and extends the life of the thermal head.
