VALID CHARACTERS

Each type of barcode has a defined set of valid characters. If an invalid character is detected for a particular code, the printer prints a pattern of all bars or a solid bar (invalid symbol) to flag that error.

The following shows the valid characters for each type of barcode:

Code 39

0 1 2 3 4 5 6 7 8 9

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

- . <SPACE> $ / + %

(Lowercase letters are printed in a barcode symbol identical to uppercase letters. The associated human readable line shows the correct case.)
