So far I have not used any barcode scanner. Therefore, I am new in this field. To install, there is not much to say, since the scanner plug-Play understands. USB in and get started. The scanner reads the bar code by CD cases and films and writes the code as indicated by the keyboard getippert in the previously unfocused field. So go really as simple as I write this. Why only 4 stars ?? Because every now and then, for whatever reason, the scanner can not focusing. There are then 2 or 3 additional tests needed. So in this regard anything hakelig what you can not bear because of the low price.
