C#实现自定义打印文字和图片的示例代码

//打印机设置
PrintDialog printDialog = new PrintDialog();
printDialog.Document = ptDoc;
printDialog.ShowDialog();

PrintDocument ptDoc = new PrintDocument();
ptDoc.DocumentName = "测试文件";//在队列中显示的名字
ptDoc.PrintPage += PtDoc_PrintPage;//关联内容生成方法

        private void PtDoc_PrintPage(object sender, PrintPageEventArgs e)
        {
            e.Graphics.Clear(Color.White);
            // 开始绘制文档
            // 默认为横排文字
            e.Graphics.DrawString("标题:打印测试",
                                    new Font(new FontFamily("宋体"), 40, FontStyle.Bold),
                                    System.Drawing.Brushes.Red,
                                    170, 10);
            // 横线
            e.Graphics.DrawLine(Pens.Black, 20, 110, 800, 110);
            // 竖排文字
            e.Graphics.DrawString("内容",
                                    new Font(new FontFamily("宋体"), 14, FontStyle.Bold),
                                    System.Drawing.Brushes.Black,
                                    20, 120,
                                    new StringFormat(StringFormatFlags.DirectionVertical));

            //e.Graphics.DrawImage(Image.FromFile(Path), 20, 250, 800, 100);    //会造成失真
 
            Image imgsample = Image.FromFile(Path);
            Point pt = Zoom(imgsample.Width, imgsample.Height, 200);
            e.Graphics.DrawImage(imgsample, 20, 250, pt.X, pt.Y);//直接打印可能出现太大打印不下
        }

        private Point Zoom(int x, int y,int maxWidth)
        {
            Point pt = new Point(x, y);
            while (pt.X > maxWidth)
            {
                pt.X /= 2;
                pt.Y /= 2;
            }
            return pt;
        }
