@JeffSchwenk code 39 does supports spaces. ""The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters (-, ., $, /, +, %, and space). "" You need to include an asterisk at the beginning and end of the information to be barcoded, so to barcode 123 ABC, the field would be *123 ABC*. Hope that helps.
