Metrologic/Honeywell MS-7120 Orbit Omni-Directional Scanner

I purchased this scanner thinking I could use it with my cash register however ever to cut a long story short it came with a USB interface meaning its for use with a personal computer.upon searching I noticed this particular model comes with two interfaces either a USB interface or an rs232 interface if you want to use on a computer you chose the USB interface if you want to use on a cash register then you would choose the rs232 interface.I contacted the maker of the scanner (honeywell) they did admit that although the scanners are the same models the only difference is that they come with different interfaces that's well that's what I thought however I am wrong apparently they are internally different so there's no way I could just buy a separate rs232 lead because I have been told I will never get the model with the USB interface to work my cash register.So now I will need to purchase another scanner this time with the rs232 interfaceI did purchase this at a really good price amazon did offer to accept it back but I decided against this I will now use it on my pc Which is what I did it's working great.It's a great scanner can't fault it performance wise if your going to purchase just make sure you inquire to see what interface that comes with it.
