Its very simple to do.

Overide OnPrint function of CTreeView and do the following:-

YourView::OnPrint(CDC* pDC,CPrintInfo* pInfo)
{
        CClientDC dcScreen(NULL);
        pDC->SetMapMode(MM_ANISOTROPIC);
        //map 1 screen logical inch to 1 printer.
        pDC->SetWindowExt(dcScreen.GetDeviceCaps(LOGPIXELSX),
                dcScreen.GetDeviceCaps(LOGPIXELSX));

        pDC->SetViewPortExt(pDC->GetDeviceCaps(LOGPIXELSX),
                pDC->GetDeviceCaps(LOGPIXELSX));

        CPen pen(PS_SOLID,1,RGB(0,0,0));
        CPen* OldPen = pDC->SelectObject(&pen);

        SendMessage(WM_PAINT,(WPARAM)pDC->m_hDC);
        pDC->SelectObject(OldPen);
}

     The above code does what you needed.

Override OnDraw in that way

void CMyView::OnDraw(CDC* pDC)
{
        if(pDC->IsPrinting())
        {
                GetTreeCtrl()->SendMessage(WM_PAINT,(WPARAM)pDC->m_hDC,0);
        }
}
