Abstract: In the present invention, the platen bar is compositely formed of three materials. For a sole layer, a material is used which has high hardness and strength, and has a property that the repulsion against the impact of the print wires is large. For an elastic layer, a material is used which transmits less vibration to the platen base in the print operation and absorbs the impact when the wires of a printhead strike the sole layer. For platen bases, a material is used which has a very high hardness, a high molding precision, and less dimensional change due to temperature change or change with time. The elastic layer is exposed on the surface and a gap roller is positioned at the exposure location. With this, the occurrence of the dent by the gap roller can be prevented when the printing on a copy form is performed.

Abstract: Rolls of printer paper are marked with information which indicates the length of paper remaining on a roll by measuring the distance between indicia successively applied by two separate print drums which each apply indicia at substantially equally spaced first and second intervals, respectively. The length of paper remaining on the roll is determinable by measuring the spacing between indicia applied by each drum. Some of the applied indicia may also be bar-coded with roll length indicia which includes a second means of determining length of paper remaining on a print roll and other information such as paper type, total roll length and name of the manufacturer. The indicia can be applied at speeds of paper travel substantially higher than the fastest known dynamic printing techniques.
