Code 39 Parameters n
5
, n
6
, and n
7
Together, parameters n
5
through n
7
are used to calculate the maximum width of Code 39
characters and the start and stop characters by means of the following equation:
[(n
5
x 5) + n
6
+ 3 + A]/144"
The value of A is determined by n
6
and n
7
:
Code 39 Parameter n
8
This parameter sets whether or not the readable characters are printed.
n
8
= 0: print readable characters in Utility mode
n
8
= 1: print readable characters in NLQ mode
