I own this. It works beautifully with my current Windows 7 operating system. It will work on many newer systems, but I was super pleased it worked on mine.
The User Guide came with this. Keep the User Guide. Do not throw out. English instructions at the beginning of the booklet were surprisingly clear.
Plug and Play works fine.
Just insert it into the USB port, give it time to quickly set up the software, then it's ready to use.
To give it a quick test run, I opened up notepad, left my curser in notepad, then scanned a few products to make sure it was reading correctly. It worked beautifully.
I am happy, this is perfect for your business.
