How to create a menu sheet
Menu sheets use the CODE39 code system. However, the code used for this reader is
special as a space mark is used as the start and stop codes. (Normally "*")
You can create a menu sheet using readily available code creation software, as shown
below.
E.g.: When creating a menu sheet "A3"
Create "* A3 *" and cut the parts of "*" with scissors to create the menu sheet "A3".
