Code 39 Properties Box Options
The table below lists the options available for Code 39 in the Properties box > Barcode tab.
Code 39
Field Description
Symbology
Select Code 39 from the drop down list. For a complete list of
available symbologies along with examples and descriptions of each,
please refer to the topic
Barcode Symbology Reference .
Extended
Select this checkbox if you want this to be Code 39 Extended
symbology. Code 39 Extended supports all ASCII characters by
using double character encoding.
Bar Width
This setting determines density of the barcode. Increase the bar
width (applies to the individual bars in the barcode) and the density is
decreased. You might want a more dense barcode to fit on a small
label, for example. Keep in mind that a barcode that is too dense
may be harder for a scanner to read and may not be scannable at all.
Char per Inch
This settings stands for character per inch. You can add more
characters per inch by increasing the number in this field, resulting in
a more dense barcode. Notice that as you increase the number in
the Char per inch field, the Bar Width field decreases. The more
characters you add per inch, the more dense your barcode will be.
Keep in mind that a barcode that is too dense may be harder for a
scanner to read and may not be scannable at all.
Bar Height
This setting determines how tall your barcode will be. The bar height
does not affect density.
Check Digit
Select the Check Digit checkbox to include an optional check digit
on your barcode to enhance data security. A check digit appears last
on the barcode and checks for errors in the preceeding content. A
modulo 43 check character can be used to enhance data security for
Code 39 symbols. The last digit of the symbol is assumed to be the
check digit, and it is compared to a calculated check digit to verify the
symbol.
Show in
Caption When this option is selected, the check digit will appear in the
barcode caption.
Ratio This is the wide to narrow bar ratio. The default setting is 2 (2:1).
Show
Start/Stop
Select this checkbox to display the Start and Stop characters in the
captions of the barcode. In Code 39 the * character is automatically
used as the Start and Stop characters. Start and Stop characters tell
a reader where the barcode content begins and ends.
Stop
Character
Select a Stop Character for your barcode or choose Auto to let
Labeler assign one for you. A Stop Character at the end of a barcode
tells a scanner or barcode reader that the content has ended. Your
options are: A, B, C or D.
