Hello, and thanks for this very simple to use module !

When generating with code39, and reading the generated barcode with a qr code scanner, it renders with an additionnal letter at the end.

Eg : generating for "B504" produces "B504K"

import barcode
Code39 = barcode.get_barcode_class('code39')
code39 = Code39('B504')
code39.save('code39_barcode')

Looks like it's the checksum digit. Can you try:

import barcode
Code39 = barcode.get_barcode_class('code39')
code39 = Code39('B504', add_checksum=False)
#                       ^ Add this argument here
code39.save('code39_barcode')
