1. A bi-directionally linearly scannable bar code pattern comprising:
- a parallel array of alternating elongated first portions and second portions;
each of the first portions having a first optical characteristic, and each of the second portions having a distinct second optical characteristic;
each of the first portions and each of the second portions having a respective selected width selected from a range of different widths;
each of the first portions comprising an elongated bar having a common series of alternating first segments and second segments;
each of the first segments having the first optical characteristic, and each of the second segments having the second optical characteristic;
each of the first segments and each of the second segments having a selected length;
the length of each first segment in the series being equal to the width of a corresponding first portion at a corresponding place in the array;
the length of each second segment in the series being equal to the width of a corresponding second portion at a corresponding place in the array; and
a substrate having an edge, including multiple instances of the pattern printed along the edge of the substrate, wherein the first segments of the first portions comprise printed portions of the substrate, and wherein the second portions and second segments comprise unprinted portions of the substrate.

Abstract
A bi-directionally scannable bar code pattern having a parallel array of alternating lines and spaces, each having selected widths. Each line has a common series of segments and segment spaces of selected lengths. The length of each segment may be the same as the width of a corresponding line, and the length of each segment space may be the same as the width of a corresponding space between lines. The pattern may be printed on a sheet of printer media, or on a strip attached to such a sheet.
