Extended Code 39 Barcode Font Demo Downloads - For Mac Users
When you review other Code 39 Barcode Fonts on the web, almost all of them refer to them as supporting the "extended" character set. Just be aware that making that statement doesn't mean that the font is any different than all the other Code 39 barcode fonts on the web. The make-up and character set of Code 39 barcodes is controlled by Mil-Spec that requires all Code 39 barcodes to support the 128 character Full-Ascii character set.
In designing our Extended Code 39 barcode font, we took a different approach. We wanted to make your job easier - to make it simple to encode all the characters on your keyboard. To make one of the keyboard characters not supported by the standard character set, you have to encode both a precedence character, followed by a standard character. We thought that to be too much work. Here's what we did:
The Code 39 character set only supports the capital letters A-Z and the numbers 0-9. If you want to encode a lower case letter, you have to use the precedence character and the normal capital letter. For example, to encode a lowercase b, you would encode the following:
*+B* - Note the stop and start character. Here's how the barcode would look:
If you look closely at the "+" in the bacode, you notice a little f sign at the bottom right. That means that this character is used for a special function. Specifically, the function is changing the capital "B" to the lowercase "b" when the scanner decodes it.
The description of how the Full Ascii Character set works for the Standard Code 39 barcode font is outside the scope of this page, but you can find a full description of its usage on this page: CLICK HERE!
Note that the "human readable" portion of the barcode looks funny. The average person reading the code won't know what it its. Also the person printing the barcode would have to understand and convert the Full ASCII character to precedence and standard characters. We felt we could solve both problems with an "Extended Code 39 Barcode Font"This .
In designing the Carolina Barcode Extended Code 39 Font character set, we were sensitive to both making the encoding process easier for the person making the barcodes, and making the human-readable portion make sense for the person looking at the code. Here's how it works:
We've taken most of the keyboard characters you would most likely use in making barcodes and made each of them available in the Extended character set - JUST BY PRESSING THE KEY. Lets take a look at what happens when you encode a character not in the standard character set. We'll use the example above to demonstrate.
On top is the precedence / standard combination. On the bottom is the Extended Character Set. Both barcodes are identical, except for the human readable portion. Code 39 barcode formats are represented by 5 bars for every character. Moving right to left, the first 5 bars represent the * start character (to the left of the orange line. The next 5 bars represent the + precedence code (first orange line to blue line). The next 5 bars are the representation for the standard character B from the standard font set (blue line to the second orange line. Finally, the stop character is represented by the final 5 bars. The stop and start characters are the same, an asterisk ( * ).
The long and short of the story is that you can just type the characters you want without having to worry about the special encoding of precedence and standard character combinations. On top of that, the printed barcode will have human readable text that means something to the operator.
Remember, in order for your barcode scanner to work, you have to program it, enabling the "Full Ascii" option for reading Code 39 barcodes. To see how to program your barcode scanner, click here..
Just like the standard version, the Carolina Barcode Extended Code 39 barcode font include tall and short formats, each of which allows the display of human readable text below the barcode. After installation, change the way the font looks by selecting "Bold", "Italic" or "Bold Italic" from the font bar.
Note that the demo fonts have the "E", "0" and "S" removed from the font set as well as the extended characters. You can still use the precedence and standard characters to make those unsupported characters to test the font. Once you purchase, you're entitled to both the standard and extended versions of the font, so the application you're using the font with will work flawlessly!
In order to make it comfortable for you to try the demo, we offer 2 methods of installation:
