Not sure if Stack is the right place to ask this, but I am trying to find out how to remove "T" prefix characters from the barcode by programming the reader.
I have struggled to find anything like this in the user manuals, but that could just be my bad reading of them! The closest thing I could find is an FN1 character substitution option, and I'm not sure if that's what I'm after.
Edit: Note that the T is an actual part of the barcode; it is the first character and I want it removed every time I scan a barcode.
