As I was trying to interpret the 'self.line' information, I realized that I have a 2-d barcode reader and I'm trying to read 1-d barcodes. Didn't completely understand "2-D". I'm so sorry for all the wasted effort. But I did learn a lot. I'll get a 1-D reader with a USB interface and try again. Hopefully I can figure it out this time around.
