推荐答案

查找使用条形码字体的内容（商业或其他）。检查您的读者是否正确阅读了它们。如果确实如此，那么你的字体有问题。如果没有，那就是你的读者。



或者，简单地说，在单独的行上打印'11111'和'33333'，彼此之下。他们看起来相同吗？如果是 - 你的字体不好，如果没有，那么你的条形码阅读器就是问题。



学习这种思维方式 - 你需要它，如果你想要变得更好，几乎任何东西。有什么问题？它是如何显示的？我该如何测试？

Find something (commercial or otherwise) that uses your bar code font. Check to see if your reader reads them correctly. If it does then there's something wrong with your font(s). If it doesn't, then it's your reader.

Or, simply enough, print '11111' and '33333' on separate lines, below one another. Do they look identical? If yes - your fonts are no good, if no, then your bar code reader is the problem.

Learn this method of thinking - you'll need it if you want to be good and nearly anything. What's the problem? How is it shown? How can I test it?
