c# 打印问题

Question

我需要在程序中实现实时打印，例如磅道，没过一车，就将计重数据打印出来，并等待下一车，直至到该纸的底部或者打够一定的数目，用控件printDocument 的Print，会打完一条数据后就退纸。有没有什么办法实现我需要的功能啊？

纸张大小没问题，我已经设到9999cm了，下面是我的代码的一部分，测试用的，比较乱，谢谢了   private void button1_Click(object sender, EventArgs e)
        {
            printDocument1.PrintPage += new PrintPageEventHandler(MyPrintDoc_PrintPage);
            try
            {
                //printPreviewDialog1.Document = printDocument1;
                //printPreviewDialog1.FormBorderStyle = FormBorderStyle.Fixed3D;
                //printPreviewDialog1.ShowDialog();
                printDocument1.Print();
            }
            catch
            {
                MessageBox.Show("请安装打印机", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }        }
       protected void MyPrintDoc_PrintPage(object sender, PrintPageEventArgs e)
        {
            //字体 颜色 格式 坐标
            drawFont = new Font("Arial", 8);
            TitledrawFont = new Font("宋体", 15);
            drawBrush = new SolidBrush(Color.Black);
            x = 0F;
            y = 0F;
            drawFormat.FormatFlags = StringFormatFlags.NoWrap;
            //线条长度
            Pen line = new Pen(drawBrush, 1);
            line.DashStyle = DashStyle.Dot; //虚线
            
            float leftbianJu = 120;
            float topbianJu = titleHeight + rowHeight * 5 + 1;
            float tableWidth = 690;
            float tableHeight = 387;
            float cellwidth = 30;
            float cellwidth1 = 66;
            count++;
            if (count == 1)
            {
                printTop(e, leftbianJu, topbianJu, tableWidth, tableHeight, cellwidth, cellwidth1, line);
                printMiddle(count, e, leftbianJu, topbianJu, tableWidth, tableHeight, cellwidth, cellwidth1, line);
            }
            else if (count < 22)
            {
                printMiddle(count, e, leftbianJu, topbianJu, tableWidth, tableHeight, cellwidth, cellwidth1, line);
            }
            else
            {
                printMiddle(count, e, leftbianJu, topbianJu, tableWidth, tableHeight, cellwidth, cellwidth1, line);
                // 尾
                printLow(count, e, leftbianJu, topbianJu, tableWidth, tableHeight, cellwidth, cellwidth1, line);
            }        }

Answer 2

那就在printdocment 的事件中一直循环你所需要打印的东西 

Answer 3

这种方式  貌似只有 把页面东西输出完，然后  printDocument1.Print();就会打印，并且 这个时候打印，会把纸切断，只是听说 什么POS/ESC 控制，我也没找到 C#方面的 资料

Answer 4

看来printDocument1.Print();是不能实现了？！

Answer 6

虽然没有找到解决办法，不过最终还是通过ESC和制表符做的（偷懒是不行滴！~~~），所以还是谢谢大家的回答，由于ruanwei1987提到了ESC，分没多少，还是给他吧。希望大家再找到能偷懒的打印控制方法，能够教我一下，谢谢了。QQ40072379
