打印预览实现流程：
首先调用CFormView::OnFilePrintPreview，再依次调用自己的所重写的虚函数OnPreparePrinting(CPrintInfo* pInfo)、OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)、OnPrint(CDC* pDC, CPrintInfo* pInfo)、CFormView::OnPrint(pDC, pInfo);，当关闭打印预览时调用OnEndPrinting(CDC* pDC, CPrintInfo* pInfo) ，结束打印。
部分代码：
ON_COMMAND(ID_FILE_PRINT_PREVIEW, CFormView::OnFilePrintPreview)
BOOL CElectronValveView::OnPreparePrinting(CPrintInfo* pInfo)
{
// default preparation
pInfo->SetMinPage(1); //设置打印文件起始页
pInfo->SetMaxPage(1); //设置打印文件终止页
return DoPreparePrinting(pInfo);
}
void CElectronValveView::OnBeginPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)
{
// TODO: add extra initialization before printing
m_ChartCtrl.GetBottomAxis()->GetGrid()->SetColor(BlackColor);//设置栅格颜色为黑色，不然打印的时候太淡
m_ChartCtrl.GetLeftAxis()->GetGrid()->SetColor(BlackColor);
}
void CElectronValveView::OnEndPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)
{
// TODO: add cleanup after printing
m_ChartCtrl.GetBottomAxis()->GetGrid()->SetColor(BlueColor);//恢复颜色，不然控件中也是这个颜色了。
m_ChartCtrl.GetLeftAxis()->GetGrid()->SetColor(BlueColor);
}
void CElectronValveView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
// TODO: add customized printing code here

本程序利用ChartCtrl来实现绘制表格和曲线。
