什么是一些好的可编程条形码扫描仪? [英] What are some good programmable barcode scanners?

问题描述

本质上，我正在寻找可以通过提供的软件或某种编程语言进行编程的一维条形码扫描器，该扫描器将读取条形码并格式化结果字符串.

Essentially, I'm looking for a 1D bar-code scanner that I can program, either through provided software or some sort of programming language, that will read a bar-code and format the resulting string.

我已经尝试过Datalogic Gryphon GD 4130扫描仪，但它不能很好地满足我们的要求，我认为他们提供的软件很难使用.

I have already tried the Datalogic Gryphon GD 4130 scanner and it didn't work well with what we needed it to do, and I thought the software they provided was hard to use.

价格也不是问题.因此，任何建议都会很棒.

Price isn't an issue either. So any recommendations would be great.

推荐答案

The Honeywell Voyager 9520/40 line worked well for me. The scanner itself was easily programmable by scanning "program barcodes" that they provided.

但是我还需要我的程序能够检测条形码扫描，即使它不是活动"窗口也是如此.而且我不想创建一个全局键盘挂钩来检查是否有任何键盘输入实际上是条形码扫描.

But I also needed my program to be able to detect barcode scans even if it wasn't the "active" window. And I did not want to create a global keyboard hook to check if any keyboard input was actually a barcode scan.

我发现霍尼韦尔提供了免费的驱动程序，可以将扫描仪的输出转换为PC上的串行端口"输入-尽管它是USB扫描仪.这对编程很有好处，因为它可以读取大多数编程语言中的串行端口数据，而且对于我来说，创建一些本机代码以读取USB端口数据对我来说很困难.

I found that Honeywell offered free drivers to convert this scanner's output into "serial port" input on the pc - though it was a USB scanner. This was good for programming because it's a cinch to read serial port data in most programming languages, and it would have been rough for me to create some native code to read USB port data.

在研究此问题时，我发现大多数扫描仪实际上都具有模拟串行端口输入的功能，因此，如果希望程序能够检测扫描而不必先获得焦点，则建议您注意该功能.

When researching this I found that most scanners actually had the capability to emulate serial port input so I would recommend that you look out for that feature if you want your program to be able to detect scans without having to get the focus first.
