SUMMARY
The Web Browser component of Internet Explorer 3.x and 4.x does not support a Print method. You can still print the contents of the Web Browser control using one of these methods:
 * Set focus to the Web Browser control and send a key combination of CTRL+P.

-or-
 * Call the GetDocument method that returns an IDispatch*. Using the IDispatch*, call QueryInterface on IID_IOleCommandTarget. With the object pointer returned, call Exec(NULL, OLECMDID_PRINT,0, NULL,NULL).



MORE INFORMATION
The following code can be used to cause the Web Browser control to print its contents. In this example, m_ctlWebBrowser is an instance of the wrapper class generated by Class Wizard for the control. m_ctlWebBrowser is contained in a dialog and initialized in the OnInitDialog function. A Print button on the dialog is wired to an OnPrint function. The Print button is enabled in response to the NavigateComplete event of the Web Browser control.

Sample Code
BOOL CAboutDlg::OnInitDialog {      CDialog::OnInitDialog;

m_ctlWebBrowser.Navigate(_T("http://www.microsoft.com"),                               NULL, NULL, NULL, NULL); return TRUE; }

First Method
void CAboutDlg::OnPrint {      CWnd* pWnd = GetFocus ;

m_ctlWebBrowser.SetFocus ; // send Ctrl-P keybd_event (VK_CONTROL, 0, 0, 0); keybd_event ('P', 0, 0, 0);

// set focus to control that previously had focus if (pWnd); pWnd->SetFocus ; }

Second Method
// DOCOBJ.H comes with the Internet Client SDK and is installed by  // default in the "\INetSDK\Include" directory #include 

void CAboutDlg::OnPrint {      LPDISPATCH lpDispatch = NULL; LPOLECOMMANDTARGET lpOleCommandTarget = NULL;

lpDispatch = m_ctlWebBrowser.GetDocument; ASSERT(lpDispatch);

lpDispatch->QueryInterface(IID_IOleCommandTarget,                                 (void**)&lpOleCommandTarget); ASSERT(lpOleCommandTarget);

lpDispatch->Release;

// print contents of web browser control lpOleCommandTarget->Exec(NULL, OLECMDID_PRINT, 0, NULL,NULL);

lpOleCommandTarget->Release; }
