Barcode FAQ & Tutorial
Some scanner manufacturers’ ship new barcode scanners with most symbologies disabled, therefore, if a particular barcode cannot be read, make sure it is enabled in the scanner's firmware.
Some barcode scanners also read different symbologies better at different sizes. For example, the Symbol Laser Barcode Scanner dependably reads the Code 39 Barcode Font when printed as small as 6 points, but only reads the Code 128 Barcode Font when printed at 8 points.

How to Identify a Barcode

Generating barcode: using font OR 3rd party program?
I always recommend interfacing with a third party bar code labeling program. The prices of these are reasonable, they offer layout design features, scaling features, compatibility with a wide variety of printers and they generally are reasonably priced.
While you can utilize fonts, you are very limited in the symbology and, depending upon how the bar code is being used and the types of controls you need, you cannot create a checksum in a font-style bar code.
In cases where the application is totally in-house (and you have more or less total control and quick access to resolve problems) or where the bar code is a convenience factor on a complex text document (as might be the case printing the invoice number on an invoice), then the use of a bar code font on a standard laser printer may be the reasonable choice. Even in these latter cases, you may want to have a QC process where you check the readability of the printed results with a sampling frequency to be determined (again) by the potential cost of an error.
