Hi,
The code is generating a file of 180 lines, I can check that with vi, but when I am executing the following command for duplex printing , it is printing 4 pages which include 2 blank pages 2 & 4 (page no).

$ lp -d printer -0 'land,double,lpi=8,length=90' filename

It is expected to print only 2 pages with content in it.
Any help is appreciated in this regard.
Thanks
DSD
