Notes:

Doesn't work on a x64 system. (i.e. this declaration is wrong for x64, I'm just not quite sure why.). MH:I tested the code extensivly and I think the param "IntPtr pDevModeInput" must not have the "ref" flag. If it has the initial state of the dialog is wrong. EP: Yup, you're right! Thanks!!! I've been trying to figure out why it doesn't work on some drivers for a few weeks now! "ref" removed.

I had similar issues under x64 so i invstigated a bit and found the sollution!

"DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, pDevMode, pDevMode, 0);" returns -1 and error code 183 under x64 however i dnt knw y!

in order to get it working use "DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, IntPtr.Zero, pDevMode, 0);"

Tips & Tricks:

Please add some!

Sample Code:

private void OpenPrinterPropertiesDialog(PrinterSettings printerSettings)
    {
        IntPtr hDevMode = printerSettings.GetHdevmode(printerSettings.DefaultPageSettings);
        IntPtr pDevMode = GlobalLock(hDevMode);
        int sizeNeeded = DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, pDevMode, pDevMode, 0);
        IntPtr devModeData = Marshal.AllocHGlobal(sizeNeeded);
        DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, devModeData, pDevMode, 14);
        GlobalUnlock(hDevMode);
        printerSettings.SetHdevmode(devModeData);
        printerSettings.DefaultPageSettings.SetHdevmode(devModeData);
        GlobalFree(hDevMode);
        Marshal.FreeHGlobal(devModeData);
    }

Sample works under both x64 and x86:

private void OpenPrinterPropertiesDialog(PrinterSettings printerSettings)

    {
        IntPtr hDevMode = printerSettings.GetHdevmode(printerSettings.DefaultPageSettings);
        IntPtr pDevMode = GlobalLock(hDevMode);
        int sizeNeeded = DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, pDevMode, pDevMode, 0);
        IntPtr devModeData = Marshal.AllocHGlobal(sizeNeeded);
        DocumentProperties(this.Handle, IntPtr.Zero, printerSettings.PrinterName, IntPtr.Zero, pDevMode, 14);
        GlobalUnlock(hDevMode);
        printerSettings.SetHdevmode(devModeData);
        printerSettings.DefaultPageSettings.SetHdevmode(devModeData);
        GlobalFree(hDevMode);
        Marshal.FreeHGlobal(devModeData);
    }
