2D Bar code PDF417 character length?

Dear All,

I am printing 2D bar code and I am getting only 255 character when I am scanning the bar code.

But I am passing around 1800 character .

Printer is printing 255 character only rest character truncated .

My Bar code parameters are in SE73-

Bar Code Symbology : PDF 417

Bar Code Alignment : Normal

Narrow Module Width : 04

Linear Height : 00300

Single Row Height : 00030

1. of Columns (1-30) : 16

2. of Rows (3-90) : 10

Truncation

Suggest me how to get rest of the character all 1800 character .Any changes required in parameters let me know.

Thanks and Regards
