Can you believe there are people who would charge you for a barcode
font like this? It took very little time to make this so I thought
I'd donate it to the world. It is suitable for scanning even at
fairly small point sizes (with a laser printer). I have tested
printed copies of this font with a couple different scanners and it
worked perfectly.

This is 3 of 9 (sometimes called "code 39"), a widely used barcode
standard that includes capital letters, numbers, and several symbols.
This is not the barcode for UPC's (universal price codes) found on
products at the store. However, most kinds of barcode scanners will
recognize 3 of 9 just fine.

To create a valid 3 of 9 barcode you have to begin and end it with
a special character. Scanners look for this character to know
where to start and stop reading the barcode. It is represented in
this font with the '*' character. So, to create a barcode for the
text "ABC123" you have to type out "*ABC123*". Note that barcode
readers will not include the *'s in the text they return. They will
just give you the "ABC123".

Two versions of 3 of 9 are included. The font called "Free 3 of 9" is
the basic 3 of 9 standard. It includes letters and these symbols: $ %
+ - . and /. The font called "Free 3 of 9 Extended" covers the
extended 3 of 9 standard. It includes all the ASCII characters.
