(4) Type of check digit
When no check digit is attached, a barcode of the data row will be drawn.
In the case of the check digit check, when each check digit check is performed according
to the type of barcode and results in normal, a barcode will be drawn. If the check digit
is not proper, the barcode will not be drawn.
When the check digit is automatically attached, each check digit is attached according to
the type of barcode when a barcode is drawn.
* DBP Modulus 10 is Modulus 10 for Deutsche Bundespost Postdienst only.
(5) Bar width, space width, and character-to-character space
Designate the bar, space, and character-to-character space widths according to the type
of barcode. Note that the designated proper value differs according to the rotational
angle of barcode, type, number of digits, print speed, paper used, etc. Examples of such
designations are listed below.
When NW7 is used, transmission of the space character assumes a space equals to 'a
narrow space ×12 dots'. In this case, the space is max. 255 dots.
