Duplexing Excel 5.0/95/97

I need to be able to force Excel worksheets to print duplex without the need to change the printer set-up whenever the workbook is closed and re-opened (Particluarly in different domains).

A VBA solution would assist as most of the printing is completed through a series of VBA modules.

This is possible in Word 6.0/95/97 using PCL commands within the Print Field, however I’be been unable to locate an Excel equivalent and I am unable to directly change the printer configuration from Excel.
