Ensure you print at a high enough resolution so the bars don't "bleed" together, which can cause scanning errors. Common Use Cases

Code 39 is "low density," meaning the barcodes can get very wide if you have a lot of data. Code 128 is much more compact. code39 fonts

There are also scaling issues. As raster (pixel-based) fonts, low-quality Code 39 fonts can become distorted if resized improperly or printed at low resolutions. This can result in "aliasing" where the distinction between wide and narrow bars blurs, causing scanner misreads. High-quality vector-based (TrueType or OpenType) fonts are essential to ensure that the bars scale proportionally without losing definition. Ensure you print at a high enough resolution

This "bi-level" (wide/narrow) scheme is what makes the barcode readable even when printed poorly. A scanner doesn't need to measure absolute widths; it only needs to distinguish between two relative sizes. There are also scaling issues

Because it behaves as a true font, generating a Code 39 barcode is as simple as changing the typeface in a word processor, label maker, or report generator. This simplicity democratized barcode printing.

Despite their utility, Code 39 fonts are not without limitations. One significant drawback is their low data density. Because each character requires a significant amount of horizontal space to accommodate the "3 of 9" wide element structure, Code 39 barcodes can become quite long. This necessitates wider labels, which may not be suitable for small electronic components or dense packing lists.
