Description
This command alters the way PDF 417 barcodes are generated and
printed.
Where
f = Feature to control and v = the value of the feature.
f = X, 58H, 88D
Set encoding X aspect.
2 ≤v ≤6
[Default]
v = 3
Note:
the X aspect is equivalent to the module width and affects the maximum
number of columns that will fit in the print zone.
f = Y, 59H, 89D
Set encoding Y aspect.
2 ≤v ≤8
[Default]
v = 3
f = H, 48H, 72D
Blank Space before and after the barcode
0 ≤v ≤255. Default is 8 dots
f = C, 43H, 67D
Set encoding columns
0 ≤v ≤30 (Values > 8 generally will not fit in the print zone)
[Default]
v = 0 (automatic mode)
If v= 0 then automatic processing is used.
When automatic processing is specified, the number of columns is calculated with the
number of code words based on the range of the printable area
.
f = R, 52H, 82D
Set encoding rows
v = 0 or 3
≤v ≤90
[Default]
v = 0
f v = 0 then automatic processing is used.
When automatic processing is specified, the number of rows is calculated with the
number of code words or the range of the printable area.
Note:
If the number of rows is specified, the number of columns must also be
specified.
Note:
The number of rows times the number of columns must not exceed 928.
Typically the row and columns should be set to 0 so that auto encoding will be used.
The X and Y aspect represent the number of dots horizontally and vertically to form the
smallest image element. Values of 2 for each produce very small elements, and are
probably too small unless good paper is used. The defaults are 3 by 9, which produce
easily readable barcodes.
f = E, 45H, 69D
Set error correction level.
If v between 1 and 40 it is interpreted as a percentage of the data.
If v is between 48 and 56 it is set to a specific level of 0 to 8.
