The scanner works immediately after it has been plugged into the USB port on your computer and requires no farther driver. Are sent the recognized barcodes as normal keystrokes. The recognition rate of the scanner is very high, but the bar code may (even printed) it not be too large - "standard" barcode function well always.
In my case it was not possible to scan the configuration bar codes from the included manual, as they were too close eineinander. The scanning of the barcodes from the monitor from the manual in PDF version, however, has worked perfectly.
