Hi, I don't have any experience with thin POS systems but some with PC based POS...

In the manual of the barcode scanner there is configuration barcodes that can be used to make different settings such as enable/disable barcode types, change keyboard layout when used in keyboard mode, and if the scanner supports serial over USB then you should be able to make that setting in the same way. Nowdays manuals comes in PDF more and more so you might need to print the pages you need to do this configuration I also bought an Epson TM-T88iii > thermal printer which has a parallel port on the back.

Sorry I can't help more with what you are looking for but hopefully the barcode scanner configuration is a start. /Christian > > I'm making a lot of newbie mistakes trying to get a test environment up and > I'd like some advice from someone who has experience with this.
