[Description] PDF417 barcode printing
m specifies column number of 2D barcode.(1 ≤ m ≤ 30)
n specifies security level to restore when barcode image is damaged.(0 ≤ n ≤ 8)
k is used for define horizontal and vertical ratio.( 2 ≤ k ≤ 5)
d is the length of data and it is consist of 2 bytes:
dL: 1st byte is lower number.
dH: 2
nd
byte is upper number.
d1…dn is barcode data.
