注意点：
1.计算image对象总页数
image.GetFrameCount(FrameDimension.Page);
2.初始化当前页，并获取指定页内容
image.SelectActiveFrame(FrameDimension.Page, m_CurrentPage);
3.设置PrintPage时间PrintPageEventArgs参数值，判断是否有额外页打印（次数是打印多页关键）
e.HasMorePages = (m_CurrentPage < m_PageCount);
基本DEMO（转载）
private Image m_Image;
private Int32 m_CurrentPage;
private Int32 m_PageCount;
private void Form1_Load(object sender, EventArgs e)
{
m_Image = Image.FromFile(".\\Test-2-Page-Image.tif");
m_PageCount = m_Image.GetFrameCount(FrameDimension.Page);
}
private void printDocument_BeginPrint(object sender, PrintEventArgs e)
{
m_CurrentPage = 0;
m_PageCount = m_Image.GetFrameCount(FrameDimension.Page);
}
private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
m_Image.SelectActiveFrame(FrameDimension.Page, m_CurrentPage);
e.Graphics.DrawImage(m_Image, 0, 0);
++m_CurrentPage;
e.HasMorePages = (m_CurrentPage < m_PageCount);
}
private void btnPrint_Click(object sender, EventArgs e)
{
printDocument.Print();
}
