Changing target printer from WebBrowser Control...

Hi,

I have an MFC app that has a Dialog containing the Microsoft WebBrowser control.

Once I have navigated to the appropriate URL, I wish to initiate a 'Print' however, I wish to change the target printer programmatically beforehand and set it back afterwards.

I loacated some source on Microsoft's MSDN for a function called 'GetPrinterDevice' that returns the appropriate hDevMode and hDevNames to the required printer; see
http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/Q166/1/29.asp&NoWebContent=1

I therefore have the following:

HGLOBAL hDevMode = NULL;
HGLOBAL hDevNames = NULL;
if (GetPrinterDevice(_T("MyPrinter"), &hDevNames, &hDevMode))
{
   const LECMDEXECOPT_DONTPROMPTUSER = 2;
   const IDM_PRINT = 6;
   AfxGetApp()->SelectPrinter(hDevNames, hDevMode);        // Default to MyPrinter
   TheDocument->ExecWB(IDM_PRINT, LECMDEXECOPT_DONTPROMPTUSER, 0, 0);
}
else
{
   AfxMessageBox(_T("Failed to select 'MyPrinter'."));
}

If I misspell the required printer, the AfxMessageBox pops up, so the function appears to be <almost> working, however, ExecWB still prints to the normal Windows Default printer!!!

Can anyone tell me where I'm going wrong???

Thanks,

James
