Code 39 symbol
Code 39 barcodes can include an optional check digit. The check digit may be encoded in the symbol, and optionally displayed in the human readable text as well.
Define check digit settings using the Checksum combo box. For more details see the video how to generate a Barcode.
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.
When a bar code 39 element is generated by concatenating fields or counters, the following rules apply:
- When is standard mode, the text to be encoded can only contain uppercase letters (A through Z), numeric digits (0 through 9) and one or more allowed special characters (-, ., $, /, +, %, and space).
- When in Full ASCII mode, the text to be encoded can contain any character up to ASCII 127.
When a value not complying with the above rules is found, the barcode is not displayed.
The human readable text can also be shown above the symbol or hidden according to the setting specified in the Text combo box.
