Code 39 can be extended to encode all ASCII characters below 128, including lower case text. Activate the Full encoding check box to enable Full ASCII mode.
Full ASCII mode comes at the expense of symbol length.

Text concatenation:
If a Code 39 barcode is created by linking fields or counters, the following rules apply:

  • In standard mode, the text to be encoded must contain only capital letters (A to Z), numbers (0 to 9) and one or more permitted special characters (-,., $, /, +,% and spaces).
  • In full ASCII mode, the text to be encoded can contain any characters up to ASCII 127.

If a value is found that does not comply with the above rules, the barcode will not be displayed.

The visually readable text can also be displayed above the symbol or hidden, according to the setting specified in the Text combo box.
