SAP Script and Simplex Printing

Hi Guru's,

Currently I have a customer statement that uses SAP Script. For some reason this document is being printed in duplex even though the setting for the printer in SAP is Simplex and Printer Setting in Windows is not set to duplex.

Where is this problem arising?

What can I do to SAP script to limit the printing to Simplex?

Thank you and appreciate your help.
