barcode reader and printer issue

Question

I am wondering if anyone encountered the issue here:

I am sending a specific string to the printer, for example: 123456789

It prints the barcode regarding that string, although I always need to play with the string otherwise the reader doesn't read exactly what I sent.

So I send: 123456789

The reader reads: 0123456780

Is there any way to send the data to the printer without having to change the format of the barcode?

Sending 123456789 to the printer, seeing that as a barcode, and then scanning that from the reader.

I'm kind of confused. Hope someone else has experienced the same issue and understands what I'm talking about.

Answer 1

It would be alot easier if you knew the barcode format that's being printed/scanned. There are different types, most of which have a fixed format.

If you know this, you may either be able to configure either the reader or the printer, or at least you would know why and how to change the barcode format, rather than "having to play with it".

One possible scenario you may be experiencing is that a UPC-A barcode can be stored as an EAN13 barcode ; EAN13 contains 13 digits while UPC-A contains 12 - but that's just a guess for now.
