Well, have you tried peeking at the documentation in the SDK? It sometimes
actually helps.

The keys to your success on setting the global and personal default
settings, are the level 8 and 9 PRINTER_INFO_* structures. Check out the
"SetPrinter" section and the "Per-User DEVMODE" section in the SDK.

Also try reading the "DocumentProperties" section. DocumentProperties has
nothing to do with setting default settings.
If you set duplex in the pDevModeInput it is also set in pDevModeOutput,
unless the printer does not support duplexing. By calling DocumentProperties
you give the driver the opportunity to fix/update/merge the changed members
with those of the driver's internal DEVMODE structure. The call is necessary
since some changes may not work correctly; the printer driver must be called
to correct the DEVMODE structure. When the document is about to be printed,
your application chould pass the merged DEVMODE structure to CreateDC

If you want to set the printer (while printing) to simplex, you should set
the DM_DUPLEX flag and specify DMDUP_SIMPLEX for the dmDuplex member. Or
else the driver will use it's driver internal default duplex setting (which
probably is simplex for standard printer drivers)
