Codabar for library and blood-bank labels
Libraries and blood banks that standardized on Codabar decades ago continue to print it for compatibility with existing scanner fleets and catalog systems.
Preconfigured for legacy systems
This experience renders at 1x module scale ("scale": 1) instead of the primary's default, matching common legacy library/lab printer output.
Example data
The generator is seeded with a bwip-js-verified valid Codabar value you can replace with your own identifier.
Workflow
Enter your identifier with the correct start/stop characters, confirm the preview, then export SVG for label printing.
Job-specific settings
Confirm which start/stop character pair (A/B/C/D) your existing scanner configuration expects before finalizing labels.
Common mistakes
Omitting start/stop characters, or using a character outside Codabar's supported set, is the most common input error.
Reference
Codabar is documented in the bwip-js/BWIPP symbology reference.

For newer systems without legacy constraints, Code 128 or Code 39 are common modern alternatives.
