Print PDF417 Bar Code
RS-232 Syntax:
GS P data NUL or X'1D;50;data;00'
where:
data
The ASCII representation of the characters to be printed.
Remarks:
Valid only at the beginning of a line. Printing will not start until a X'00' is
received.

This command will increment status byte 6.
The maximum number of characters to be encoded is 1000.
Error Conditions:
If an image cannot be printed, status byte 7, bit 2 will be set. This may
happen when the image is too big to print. Try decreasing the ECC level.

Select PDF417 ECC (Error Correction Codewords) Level
RS-232 Syntax:
GS R n or X'1D;52;n1;n2'
where:
n1
The high-order byte of the ECC level.
n2
The low-order byte of the ECC level.
Default:
n1 = 00
n2 = 15
Range:

Remarks:
For 0
≤ n1n2 ≤ 8, the ECC level is assumed as that particular security level.
The security level determines the number of error correction codewords
added to the symbol.
