推荐答案

除非扫描仪配置为提供前缀和后缀代码，否则不能。好消息是大多数都可以 - 但是你如何配置它因制造商而异。 （对于一些人来说，只是扫描正确的条形码的情况）



看看制造商的网站 - 他们应该有大量的相关信息！

You can''t - unless the scanner is configured to supply a prefix and postfix code. The good news is that most can - but how you configure it differs from manufacturer to manufacturer. (For some, it''s just a case of scanning the right bar code)

Have a look at the manufacturers website - they should have loads of relevant info!

更好的解决方案是使用不属于键盘楔形类型的条形码扫描仪。 USB，串行甚至基于以太网的解决方案效果更好。

The better solution is to use a barcode scanner that is not of the "keyboard wedge" type. USB, Serial or even an Ethernet-based solution works better.
