Changing a printers "global default" settings programatically on WinXP

Hi all

I've done a cross post on this reply tomyself(!) because I cant find an
appropriate group to post this on.

OK i've dug a bit futher an can confirm that when I use GetPrinter to get
the PRINT_INFO_2 data from the printer is the duple mode is set the correct
value is returned

If it is not set the I change the DevMode.dmDuplex value and then pass it
through DocumentProperties

Move
(DocumentProperties(0,hPrinter,AddressOf(sPrinterN ame),ppi2.pDevMode,ppi2.pDevMode,(DM_IN_BUFFER+DM_ OUT_BUFFER)))
to iFlag

When it comes out the other side of this dmDuplex is still set how I set it

I then call SetPrinter with the full PRINT_INFO_2 data and it returns non
zero ie succeeds

Move (SetPrinter(hPrinter,2,pPI2_Data,0)) to iFlag

BUT the duplex value when I go and check in the property panel of the
printer has not changed ????

Any help with this would be greatly appreciated !

Thanks

Andrew

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)

Thanks VERY much for the pointer !

I was fooled by the KB article entitled "How To Modify Printer Settings by
Using SetPrinter" ..... doesn't actually change anything !

I've now read both your suggested sections (properly!) and provisionally
have got it to work now that i'm doing it correctly !

Would I be correct in assuming that if I use the PRINTER_INFO_9 to change
the personal defaults this would work best with a network shared printer as
opposed to the global PRINTER_INFO_8 ?

Thanks again for all your assistance

Kind Regards

Andrew

I actually do not know. My best suggestion is to try it. Make sure to test
from an account that is NOT administrator.
Some thoughts:
As a normal user, you might only have access to set your personal settings.
When changing the global settings (level 8) it will change the "global"
settings on your local machine (I think), but it might also be that the
global settings are changed on the server (the machine where the printer is
attached) globally. Also there might be a difference depending on if the
global settings are set from a local administrator or domain
administrator....

You are welcome.
