This article relates to the Dobson Software Crystal Reports UFL
One of the biggest problems people run into with the Code 128 Crystal UFL is they do not make their field size large enough to contain the barcode at the given font size.
The fact is, just looking at the bars, who would know if a bar is missing at the end or not? Well, I could tell, and there are others out there that can tell, only because we've looked at A LOT of barcodes in our time.
If your testing the Crystal UFL, please remember to enlarge the fields, even bigger than you think you need to. The demo version adds text at the end (it is a demo, after all,) so that requires the fields to be even bigger.
