How to create print button in C++/MFC

// l've done this code in Onprint;

void CGCAppView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
	// TODO: add customized printing code here
	ASSERT(pDC);
	ASSERT(pInfo);
	// do some default output onto the page
	CString	text;
	CSize	csText;
	CFont* pOldFont;
	CFont	myFont;

	int fontSize = -MulDiv(18, pDC->GetDeviceCaps(LOGPIXELSY), 72);
	VERIFY(myFont.CreateFont(fontSize * 2, 0, 0, 0, FW_NORMAL, FALSE, FALSE, FALSE,	DEFAULT_CHARSET, OUT_TT_PRECIS, CLIP_CHARACTER_PRECIS, DEFAULT_QUALITY,FF_ROMAN,L"Arial"));
	pOldFont = pDC->SelectObject(&myFont);
	pDC->Rectangle(pInfo->m_rectDraw);
	pDC->Ellipse(pInfo->m_rectDraw);
	text.Format(L"PAGE %1d of %1d", pInfo->m_nCurPage, pInfo->GetMaxPage());
	csText = pDC->GetTextExtent(text);
	pDC->TextOut(pInfo->m_rectDraw.left + (pInfo->m_rectDraw.Width() - csText.cx) / 2,
		pInfo->m_rectDraw.top + (pInfo->m_rectDraw.Height() - csText.cy) / 2, text);
	pDC->SelectObject(pOldFont);
	VERIFY(myFont.DeleteObject());
	pDC->TextOutW(400, 200, L"Hello Mfc");
	CString alfa;
	alfa = L"this is a test string";
	pDC->TextOutW(400, 300, alfa);
	//pDC->DrawText();
