dddd Width of all Bars and Spaces.
Includes Number of Dots in: Narrow Bar, Narrow Space,
Wide Bar, Wide Space; respectively.
Range of d is 0 to F (0 to 15 dots).
ccc...c Characters to be Bar Coded.
^G Sequence Terminator.
Required to signal end of character data.
When defining a variable width bar code, first choose a bar code type that matches
the desired bar code. Then specify the width of the bars and spaces to achieve the
desired bar code density and wide:narrow ratios.
Example:
Bar code type “a” defines a rather dense Code 39 bar code with 1:1:2:2 ratio.
