I just bought a barcode reader from China model Honeywell HH400. It works perfectly when I use it other device. But now I use it in my web application and I am getting a problem. It always toggle Chrome developer console. I also tried scanning barcode into URL bar, and it does the same. Does it have an event to trigger F12 what? Or misconfiguration with the scanner that I don't know?

I am sure that you might have already received a solution. But for others who might come across this issue,
I ran into this problem today and found that no matter what prefix or suffix I try, on every browser it emulates pressing F12 which opens the browser console.
The same barcode functioned as required a couple of weeks ago.
Every barcode comes with a quick start guide that you can use to set prefix suffix etc.
There is also a bar code that "Recalls Defaults". Just scan that and you should have the factory defaults set.
This resolved my issue. Hope it helps someone.
For me the solution was to remove the "Line Feed" suffix ( which was not removed when I scanned the "remove all suffixes" code ), as the line feed is interpreted as CRTL-J on windows machines ... no idea why !? ( no time to research it either ;)
