Do you need to install a driver for barcode scanners? This is a problem that many scanner users often ask. Now Xiaobian will tell you: no, no, no, no.
The barcode scanner is basically divided into three interfaces, namely serial port (RS232), PS/2, USB. Under normal circumstances, these three types of interfaces do not need to be installed to use the driver, but there are some special. For example, the USB interface is divided into three modes: USB keyboard mode, USB serial port mode and USB HID mode. The USB keyboard mode does not need to be installed. The USB serial port mode and USB HID mode need to install the corresponding analog driver.
1) USB keyboard mode: This method is similar to USB keyboard. After connecting the computer, the bar code data will be input to the location where the computer cursor is located, whether it is EXCEL, WORD, Notepad, etc., as long as the keyboard can be input. The place can be, the USB keyboard does not need to be driven, and the natural USB keyboard mode scanner does not need to be driven. About 80% of them are in this way.
2) USB serial port mode: This mode is mainly used in the factory or software requirements is the serial port transmission mode, this way needs to install the driver, this driver is the USB to serial port chip driver, some will be divided into 32-bit drive according to the system And 64-bit drivers. If you want to scan the QR code containing Chinese, you must use the serial port to scan. If there is no corresponding software to receive the data, you need the small software "COM_Text_V1.5 serial Chinese output tool" to transfer the data received by the serial port to the cursor. .
3) USB HID mode: This mode is similar to the USB serial port mode, and it also needs to install the driver, and special software to receive data from the HID interface.
