Unable to generate a Code 128 barcode with an A rating.

We are using the Code128 font set (does not matter which version) although the Code 128XL seems to work the best. I am printing a 13 digit (GTIN) number to generate the bar code. I have tried the A, B and C versions of the UFL generator. We are printing to a Datamax O’Neil H-4212X. It only has 203 DPI available.

When we print the form out of Crystal 2008, the barcode will only scan with a B rating. If I send it to the HP Laser Jet with a higher DPI, I am able to get A ratings. They have Label Matrix software and that is able to generate A ratings on the same type of bar codes.

We have settled on 21 point font as that seems to be the best choice of between 16-24. Some of those bar codes would not scan at all.

Any advise as to how to get an A rating on a Code 128 bar code with 13 digits to a Datamax O’Neil H-4212X at 203 DPI?

Operating System: Windows 7

In general, it is recommended to keep the text object bigger than expected (if possible), since the width is the variable component of a barcode and the XL (size designation) refers to the height.

For more information on height and point size, see the Code 128 Barcode Font Specification tables.

I have done what the document said but I have a couple of questions on the bar code in Crystal Reports. I would like to use the Code128XL for the height. Does it make a difference the width of the text object in Crystal Reports? So, I figure to get a 2.2inch font based upon 13 characters and the start, check sum and stop characters. Do I need to size the text object to around 2.2 inches or can I leave it at 3.5 inches?

IDAutomation has a Knowledgebase article on printing to 203 dpi (dots per inch) printers that will be useful.
