Cristiano,
Thanks for the reply. Gotcha --- so I just bung it on the device and hey presto right? Yes, the screenshot in my original post is from my Windows laptop. Thanks a lot --- this should be enough for me to work on. By the way, none of the hits I've got about it on Google specifically mention dedicated barcode scanners --- to my mind, they all refer to using mobile phones etc. as scanners. I'm guessing dedicated machines count, in this case...? Have you got any experience of this?
