Font Name

Selected font for the caption.

This font can be a standard font (different from the bar code font) so it can be easily read.

 

Point Size

Size in which the  caption font will display.

The caption font displays within the space allocated for the bar. Therefore, the larger the font the more space it uses and the less space there is to display the bar. You can increase the space for the bar or decrease the font size if the bar is smaller than you want.

 

Location

Caption font position relative to the bar.

Options for Code 39 symbology include

Option

Description

Full ASCII

Standard Code 39 contains only 43 characters as follows.

0-9

A-Z

$

/

%

+

Code 39 can be extended to an 128 character symbology (full ASCII) by combining one of the special characters ($, /, %, +) with a letter (A-Z) to form the characters that are not present in the standard Code 39 symbology.

Example

In standard Code 39 a lowercase a cannot be represented.

In Code 39 Full ASCII a lowercase a is represented as +A.

Check Digit

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; it is compared to a calculated check digit to verify the symbol.

Append

It is sometimes advantageous to break up long messages into multiple, shorter symbols. If the first character of a Code 39 symbol is a space (ASCII 32), then the scanned symbol is appended to a storage buffer. This operation continues for all successive Code 39 symbols with a leading space being added to previously stored ones.

When a Code 39 symbol that does not include a leading space is scanned:

  1. The symbol appended to the buffer

  2. The entire buffer is transmitted

  3. The buffer is cleared.

  1. Click Apply.

  2. Click OK.

Result: The bar code displays your static text specifications.
