>I've a sales invoice screen where I can the barcode of my products to replace represent the product code.
>Barcode is mainly all digit (up to 16 digit in length) and we frequently hit problems where the values shown on the screen has some numbers changed to characters, e.g. 8 becomes a B or zero becomes O and recently, 3 becomes 8 etc.
>Have changed scanners and replace with new ones, still same issue.
>My questions are,
>1) in the field that accepts barcode values, will the font setting affect the barcode?
>2) What could be the cause of the error in barcode scanned besides scanner issue?

>The barcodes looks clear and shouldn't be a bar code printer problem.
>Hope someone can assist.
