<p>If you have a dialog based application and want to print, then you
cannot take advantage of the Doc/View framework that MFC provides to
do all the dirty work for you.

<p>In order to keep the MFC doc/View feel I recomend providing helper
functions <b>OnBeginPrinting</b>, <b>OnEndPrinting</b> and <b>OnPrint</b>
similar to the CView versions. A <b>CDC</b> and a <b>CPrintInfo</b> object 
is passed into each of these functions.

void CMyDialog::Print() 
{
    CDC dc;
    CPrintDialog printDlg(FALSE);

    if (printDlg.DoModal() == IDCANCEL)         // Get printer settings from user
        return;

    dc.Attach(printDlg.GetPrinterDC());         // Attach a printer DC
    dc.m_bPrinting = TRUE;

    CString strTitle;                           // Get the application title
    strTitle.LoadString(AFX_IDS_APP_TITLE);

    DOCINFO di;                                 // Initialise print document details
    ::ZeroMemory (&di, sizeof (DOCINFO));
    di.cbSize = sizeof (DOCINFO);
    di.lpszDocName = strTitle;

    BOOL bPrintingOK = dc.StartDoc(&di);        // Begin a new print job

    // Get the printing extents and store in the m_rectDraw field of a 
    // CPrintInfo object
    CPrintInfo Info;
    Info.m_rectDraw.SetRect(0,0, 
                            dc.GetDeviceCaps(HORZRES), 
                            dc.GetDeviceCaps(VERTRES));

    OnBeginPrinting(&dc, &Info);                // Initialise printing
    for (UINT page = Info.GetMinPage(); 
         page <= Info.GetMaxPage() && bPrintingOK; 
         page++)
    {
        dc.StartPage();                         // begin new page
        Info.m_nCurPage = page;
        OnPrint(&dc, &Info);                    // Print page
        bPrintingOK = (dc.EndPage() > 0);       // end page
    }
    OnEndPrinting(&dc, &Info);                  // Clean up after printing

    if (bPrintingOK)
        dc.EndDoc();                            // end a print job
    else
        dc.AbortDoc();                          // abort job.

    dc.Detach();                                // detach the printer DC
