Bar Codes on Inventory Labels

[Me2500]

Using MS Access 2003

We are creating labels for our upcoming inventory. We currently have a Crystal Reports label that uses font format Code 128AB to create the bar code.

We need more information on the label, so I'm trying to create one in MS Access. For my bar code I am using the formula

=BarCode128([Material])

as the Control Source and "Code 128 AB" as the font for the bar code. These are the same formulas that are used in the crystal report.

The problem is that when we scan the bar code we get an error "Out of Spec Code" on the majority of scanners (but not all), especially the one we use for inventory.

Why would an "Out of Spec Code" appear on some but not all scanners? Using Access, how do I create an 'in spec' code?

the 128 code generates a variable length code (bar set) so the physical dimensions are the prime suspect when this code is not read bt the scanner. One 'trick' is to figure out how wide a bar your bar coders can read, and place visible indicators on your bar code label to indicate wheather the generated/printed bar code is within these limits.
