I believe that many people have seen scanners in shopping malls or supermarkets. The use of bar code scanners (referred to as bar code guns) in various industries has become very common. But for the novice may still be a bit confused, what is the use of the scanner? If you are using the usb interface, your use is very simple, you just need to connect your device, you can use it, you don't need to learn any theoretical and practical knowledge to complete.
What is the use of the scanner? General testing or a simple understanding of the bar code gun to use the steps is very simple, the steps are as follows:
1. Insert the scanner (until you hear the prompt to install the barcode scanner)
2, open EXCEL (or any software that can input text)
3. Position the cursor on the cell to be entered.
4, scan the barcode (set the scan mode of the barcode gun as needed, such as carriage return, line feed, continuous scan after scanning)
5, the scan is completed, save. How to use a simple barcode scanner is very simple. A barcode gun is just a device for reading barcode content, and barcode content is just a series of numbers or alphanumeric combinations.
    If you need to print barcodes, then you need to install a barcode production software, you can also use CorelDRAW, but there are many barcode encoding methods, users need to know which barcode you need to use in your barcode. Why is the barcode gun required to be set? The following is a typical example. If the machine is normal, you can install this step to judge:
    Newly bought a 9-pin serial barcode scanner, which has been tested and proven to be used in cash registers, how to use barcode scanners, barcode scanner itself has no problem, now want to access the computer, used in Word, Excel and other documents, has bought external Power cord, 9-pin serial port pci expansion card, and installed serial port driver, after not considering the hardware problem, still can not enter data on the computer, it should be the problem of setting up, what computer do you use? Why install PCI? Expansion card, general desktop computer has 9-pin serial port. If the expansion card is installed separately, the port used by the scanner should be reset. The serial port on the computer motherboard is usually COM1 and COM2, and the additional serial port will be COM3. The bar code scanner scans the bar code with sound, which means there is no problem with the bar code scanner power supply. It is no problem to read the bar code, but it is not displayed. The problem may be in the setting of your keyboard interface or barcode scanner. The widespread application of bar code scanning technology in the global retail industry in recent years has undoubtedly reduced the amount of time that humans and customers wait in line. This is the result of human exploration and research on high efficiency. The wireless barcode scanner must be in serial mode. If the settings are incorrect during use, please scan the “Restore Factory Settings†and “Serial Port Mode†barcodes in the manual P9. To set the scanner to a channel, you must first register the channel on the host (ie the receiver), otherwise the data scanned by the scanner will not be transmitted to the host.
    The above is for you to share the use of the scanner. Have you learned how to use the scanner?
