Zebra printing S_LZPL_SETUP = ^FWR & ^LRY

We are trying to design zebra labels, using SAP smartforms. Due to the label orientation in printer, I have to use S_LZPL_SETUP as '^{FWR', in my smartform, as per the documentation available at Zebra.com. In the documentation, it is also told, to use '}LRY', for text reversing. But, when I try to include another command window and include '^LRY', smartform throws me an error saying "Value of spool attribute S_LZPL_SETUP cannot be changed.". In such a situation, how can we put in more than one command, for S_LZPL_SETUP attribute?

Requirement is to change the orientation of the output, which I am able to do, using ^FWR; and to reverse only <b>one</b> window, in the output.

Thanks,

Juwin.
