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.
