SAP ABAP Smartform Print Problem

I am facing a strange issue while printing a smartform at the user location. There is a black box covering the entire lower portion of the page.In the smartform a window is placed at this position. When I delete the window and print it, the output is fine. I have checked the option of window shading color as well âs whatever color/no color I give, it doesn't make any difference.

This happens only in a certain type of printer at the user's location ând  everywhere else its fine.

Please give some pointers âs is this a printer fault or can something be changed in the smartform to solve this problem?

Ans : I think smart forms are some how printer specific, It is not a must that if tested on one printer it will work perfectly well on the other. I always face similar problems with logos coming upside down on some printers or being very faint etc.
so its usually a printer problem. Try changing the drivers of that printer especially to a lower version and see.
