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.

I have the same issue but I cannot see the "solution" in your answer ?! I removed all suffixes but it still seems to send the "F12" command after every scan. – minychillo Feb 25 '20 at 11:02
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 ;)
