This parameter allows you to define your barcode's width based on the encoding of (numeric or alphanumeric) characters.
You can choose the unit to use: micron, mil (milliinches), mm or inch.
For example, choose mm and use 1 Character per unit in the Dynamic Barcodes dialog if you want the bars needed to encode one character to take up 1 mm.
Increase the Characters per unit value to make the barcode narrower, or decrease it to make the barcode wider. For example, if you choose 0.5 Character per unit, the bars needed to encode one character will take up 2 mm.
Note: Barcodes like Interleaved 2 of 5 encode two characters together in a
group of black and white bars. For these barcodes, Dynamic Barcodes takes half of the group of black and white bars to measure one
character.
