Barcode scanner using USB keyboard output is a common interface and data transmission method. In this mode, the scanning device simulates keyboard input and sends the scanned barcode data as keyboard key messages to the computer. The following is a clear description of the barcode scanner USB keyboard output:

Interface type: USB interface is one of the most widely used interfaces for barcode scanners, especially USB keyboard output mode. It allows the scanning device to be directly plugged into the USB port of the computer through a USB connection, realizing plug and play.

Working principle: When the barcode scanner is in USB keyboard output mode, it simulates the behavior of keyboard input. When a barcode is scanned, the device converts the barcode data into keyboard key messages and sends them to the computer through the USB interface.

After receiving these key messages, the computer will regard them as input from the keyboard and insert the corresponding data at the current cursor position.

Features: Plug and Play: USB keyboard output mode usually does not require the installation of additional drivers, just connect the scanning device to the USB port of the computer to use it.

Easy to use: Due to the simulated keyboard input, USB keyboard output mode is suitable for a variety of software and applications that support keyboard input.

Direct Data Input: Scanned barcode data can be directly entered into a computer text box, spreadsheet, or other place where data is required.

Configuration and Testing: Before using the USB keyboard output mode, you need to ensure that the scanning device is configured correctly. This usually includes selecting the correct interface mode (USB keyboard output) and setting other related parameters (such as scanning speed, data format, etc.).

When testing the USB keyboard output function, you can open a text editor or similar program, position the cursor to the input position, and then scan the barcode. If everything is normal, the scanned data should be displayed directly at the cursor position.

Note: Although the USB keyboard output mode is simple and easy to use, it may require additional processing in some cases. For example, if the scanned barcode data contains special characters or formatting requirements, you may need to use the software tools provided by the scanning device for post-processing.

In addition, if multiple keyboards or similar input devices are installed on the computer, you may need to ensure that the USB keyboard output of the scanning device is not mistaken for input from other devices.

The USB keyboard output mode of the barcode scanner is a simple, easy-to-use and widely supported way to transfer data. By properly configuring and testing, you can ensure that the scanning device can smoothly input barcode data into the computer.
