When you can't make it work? You in the front desktop? Create a notepad? Then? Open it? Scan an item with the code scanner to see if it gets in? If it does? That means the scanner's not broken? It must be a problem with the cash register software. If the scanning is intermittent even in Notepad? Then it must be a problem with the software. The scanner is broken
User name is wuweushui? I don't know what to say, so don't talk nonsense. There is no driver for the scanner gun. There are two types of interfaces for the scanner gun, one is USB and the other is with a USB port. One is USB and the other is a serial interface with the keyboard. The driver is not required.
