Setting bar code PDF-417 parameters
[Code]
[1Dh] + [70h] + n1 + n2 + n3
[Range]
{0 <= n1 <= 255}
{0 <= n2 <= 30}
{n3=0; 3 <= n3 <= 90}
[Outline]
n1
selects PDF-417 security level. Setting a security level higher than eight forces the printer to
automatically adjusts the security level according the following table:

• Only real data codewords in the security level calculation (any pad codewords are ignored).
n2
– number of data columns. If
n2
=0 the number of data columns is automatically calculated.
n3
– number of rows. If
n3
=0 the number of rows is automatically calculated.
[Caution] If any value is out of range this value remains unchanged. Thus the other values are changed.
[Default] The initial value of n1 is “9 ” (auto select).
The initial value of n2 is “0 ” (auto select).
The initial value of n3 is “0 ” (auto select).

Printing of raster bit image

[Range]
{0 <= m <= 3; 48 <= m <= 51}

[Outline] The value of xH is ignored.
Although yH could be from 0 to 255 the high four bits are ignored, so yH could actually be from 0
to 15.
xL is the number of bytes in horizontal direction (xL*8 dots).
The number of dots in horizontal direction is equal to yL+yH*256.
The number of data bytes k=xL * (yL+yH*256). However k must not be equal to 0 or the bit
image will be discarded.
m defines the printing mode of the bit image according to the following table:
