Barcode W1q
W1R: UCC/EAN Code 128 K-MART NON EDI
Valid Characters: 0-9
Length: 18 digits
Valid bar widths: The fourth character of record is the width of the narrow bar in dots.
All other bars are a ratio of the narrow bar (2, 3, or 4 times the narrow bar width).
Human readable characters for this bar code are printed above the symbol.
This produces the same symbology as bar code ID “R”, except that the human readable
field has been modified to print underneath the bar code (see below).
