Thans for your info., It was useful very much.

I identified the problem.
I have the 132 col printer , Epson Ex-1000. On that it shows all the 132 col. in the preview correctly.
But my client has Epson LQ 1170 ESC/P2 , though it is 132 col printer, it does not show the 132 col in preview completely, and shows 80 col only.
When I checked by installing both above pdrivers, one shows correctly and the other does not show.

He must have installed the P.Driver wrongly, that I will checkup and tell you correct reason.

With Luv,
Satya
