调试易

拉一个printDocument控件到界面。 
打印按钮的代码： 
C# codeCode highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/        private void button2_Click(object sender, EventArgs e)//执行打印        {            PrintDialog MyPrintDg = new PrintDialog();            MyPrintDg.Document = printDocument1;            if (MyPrintDg.ShowDialog() == DialogResult.OK)            {                try                {                    printDocument1.Print();                }                catch                {   //停止打印                    printDocument1.PrintController.OnEndPrint(printDocument1, new System.Drawing.Printing.PrintEventArgs());                }            }        }
另外还要设置PrintPage事件：
C# codeCode highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)        {            e.Graphics.DrawImage(pictureBox1.Image, 20, 20);        }

先在界面上拖入printDocument控件，然后打印事件中写：byte[] input = new Byte[100000];//读取图片
FileStream fs = new FileStream(@"图片路径", FileMode.Open, FileAccess.Read);
fs.Read(input, 0, 100000);//设置打印页面
printDocument1.DefaultPageSettings.Landscape = true;//向打印页绘制图片
Image image = Image.FromStream(fs);
e.Graphics.DrawImage(image, 20, 20);//打印
printDocument1.Print();

在printDocument1_PrintPage事件中，参数PrintPageEventArgs e有个HasMorePages属性(获取或设置一个值，该值提示是否打印附加页),通过控制这个属性值来实现多页打印
private int printIndex=0;  //打印索引，下面调用要用到
private int pageSize=3; //有三张图片要打印        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            if (printIndex < pageSize)
            {
                e.Graphics.DrawImage(Image, 0, 0, photoWidth, photoHeight);
                printIndex++;                //如果打印的页数还不足3页,那么我要继续打印
                if (printIndex < pageSize)
                {
                    e.HasMorePages = true;
                }
            }
            else
            {
                e.HasMorePages = false;
            }
　　　}
