Bug in barcode 3of9

Postby innovasrl » Tue Feb 05, 2013 9:26 pm

I've found a bug in printing the following bar code using Code39 with VPE (using Python if it matters).

"GE2XYMJV"

Reading back the code with a barcode reader I get "GE2XYMJV%" with an added "%" trailing char (obviously not requested!).

The text under the barcode is correct.

The same barcode printed using Code128 works fine.

So, I suppose there must be something wrong with barcodes printed using Code39.

I rather think - without further testing - that this is the checkdigit you are reading.

You can turn off checkdigit generation using the property BarcodeAutoChecksum.

Thanks, that solved the problem.
I'd suggest this should be off as a default. Just an opinion of course.
