代码39条形码“1”扫描仪很难读取
附件是“1”的条形码图像。有些扫描仪似乎很难阅读此内容。我的没有。为了解决这个问题，您建议做什么？
我的数据库中的项目是 1,2,3,4...等自动递增。
Attached is the image for "1" as a barcode. Some scanners seem to have a hard time reading this. Mine does not. What do you recommend to do in order to fix this?
Items in my database are 1,2,3,4...etc auto increment.

不确定这是否是您所看到的，但某些扫描仪默认配置为仅读取长度至少为两个字符的 Code 39 条形码。别问我为什么，我也不知道。无论如何，您应该能够找到扫描仪的配置设置，告诉它读取任何长度的条形码。
Not sure if this is what you are seeing, but some scanners are configured by default to only read Code 39 barcodes that are a minimum of two characters long. Don't ask me why, I don't know. In any case, you should be able to find a configuration setting for the scanner to tell it to read any length barcode.
看起来你的字符间距是两个空格宽。你有没有尝试过把它收紧一点？一些扫描仪对它很挑剔，尽管它并不正式等于 1 个窄白条。
Looks like your intercharacter spacing is two white spaces wide. Have you tried tightening it up a little? Some scanners are picky about it even though it isn't officially equal to 1 narrow white bar.
我在任何小于 10 的数字前面标记了“0”。这似乎解决了问题，而客户无需调整扫描仪。
I tagged a "0" in front of any numbers less than 10. This seemed to solve the issue without customer's having to tweak their scanners.
