Generates general Code 128-B, without GS1 data structure or product-number registration. Keeps ten-module quiet zones on both sides. The screen preview may shrink; SVG uses the shown dimensions and PNG is twice that size. Keep the margins and test printed labels with your intended reader. Black on white is preferred; avoid red bars for red-light scanners.
