Essentially it translates each character to a unique set of lines .
There is also the option of using barcode font where the char is again represented by lines

To add on to what John started with.

Each different type of bar code is called a symbology

That describes the pattern used to encode each character, any special rules like check digits (a hash function to ensure that all characters are read), guard characters (indicates the start and end of the bar code), densities allowed (how small or large it can be printed), etc.

The encoding may not only be the pattern of light/dark bars, but also the width and placement of those bars.  

Some symbologies work better with certain characters than others.

"3 of 9" and "2 of 5" are two very popular symbologies.

3 of 9 is alpha numeric, where 2 of 5 is strictly numeric, but you can push the density down on 2 of 5 a lot more than you can with 3 of 9 (because it encodes characters differently).

There are two basic ways to print a bar code with Access:

1. Using a font

2. Using a 3rd party product.

When using a font (some of which you can find for free), it is up to you to know all the rules for printing the bar code.   For example, with 3 of 9, the asterisk is required as a guard character before and after the data.   It would be up to you to insert that.

With a 3rd party product, all that is done for you.  You just place the data in the control and it handles everything.

 One such is:  http://www.idautomation.com/barcode-components/access-native/

 I've been using their add-in for many years and it works great.  There are others out there as well.

Jim.

I will add that there is a 3rd option ...using VBA code to produce barcode...
I am afraid i cannot provide any link since its against EE policy but googling it is easy and will get you there.
