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

Tagged With:-

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 barcode. 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 LaserJet with a higher DPI, I am able to get A ratings. They have Label Matrix software 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 between 16-24. Some of those bar codes would not scan at all.

Any advice 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?

James	Best Answer 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. Posted 10.8 year(s) ago (0) (0) Report Abuse

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 Code128XL for the height. Does it make a difference in the width of the text object in Crystal Reports? So, I figure to get a 2.2-inch font based upon 13 characters and the start, checksum, 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.
