这是我在这个网站上的第一篇文章，似乎无法解决问题。

如何模拟键功能 Ctrl+B 到条码，这样我就可以用扫描仪扫描条码而不按 Ctrl+B。我试过阅读 ASCII 控制代码ASCII control codes 请帮帮我。

【解决方案1】：

正如您的一个标签所展示的，您已经知道代码 128 符号系统。您将需要使用 code128A 起始码 (103) 和与 code128B (66) 中的小写“b”相同的字符。最后，在添加额外数据后，正确计算校验和并将其与停止代码 (106) 一起添加。以下 HTML 说明：

要进行测试，请打开写字板或任何使用“Ctrl-B”打开和关闭粗体文本的文字处理器。扫描 sn-p 中条形码的打印副本。每次扫描时，您应该会看到文本“TEST”在粗体和普通样式之间交替出现。

如何删除“测试”文本？
HTML 由 8 个标签构成。事实证明，“Ctrl-B”的校验和字符也是“Ctrl-B”（66）。所以，对于sn-p中的9行，保留第1行（开
