How to check if the barcode scanner can be used
How can I detect if a barcode scanner is usable? In general, the bar code scanner will be accompanied by a manual when purchasing, please refer to the manual whether you need to install the driver. At present, most barcode scanners do not need to be installed with a driver, and can be used by directly plugging them into a computer.
Whether it is a USB interface, a serial port (a 9-pin port), or a keyboard port, just plug it into the computer (if necessary, please install the driver), the bar code scanner light will light up. After sweeping the barcode, it will produce a squeaky sound. Please open Notepad or where you can type words (like Word, Excel), then scan a product barcode to see if barcode numbers appear. If a bar code number appears on the computer, it means that the bar code scanner is normal and can be used. Otherwise, please check the problem. If necessary, contact the supplier of the scanner to resolve the issue.
As shown below, after scanning the item, it will appear in Notepad:
