小票打印,该如何解决

小票打印
80mm的纸张还有57mm的纸张其中80mm的纸张要求能发送进纸、退纸、切纸的命令
弄了有一段时间了` 切纸的命令怎么也实现不了`就是不能控制打印机什么时候切纸`
每次切的时候都会切到字。

关注一下，这几天我也在做打印小票的程序

我之前做过的练习分享一下
C# code
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Drawing.Printing;namespace WindowsApplication1{    public partial class Form1 : Form    {        string passWord = "1234";        string fullnumber = "9999";        System.Drawing.Printing.PrintDocument pdBays = new System.Drawing.Printing.PrintDocument();        public Form1()        {            InitializeComponent();            pdBays.PrintPage += new PrintPageEventHandler(pbay_PrintPage);            pdBays.DefaultPageSettings.PaperSize = new PaperSize("",600, 800);        }        private void button1_Click(object sender, EventArgs e)        {            for (int i = 0; i &lt;= 0; i++)            {                pdBays.Print();            }        }        public void pbay_PrintPage(object sender, PrintPageEventArgs ev)        {            Graphics dc = ev.Graphics;            Pen pen = new Pen(Color.Black, 1);            Font drawFont = new Font("仿宋_GB2312", 12);            SolidBrush drawBrush = new SolidBrush(Color.Black);            PointF drawPoint = new PointF(30, 200);            //这句可以隐藏“正在打印”窗体            pdBays.PrintController = new System.Drawing.Printing.StandardPrintController();            dc.DrawString("\n密码：" + passWord + "\n充值券编号：" + fullnumber, drawFont, drawBrush, drawPoint);        }        ////网上例子        //private void btnPrint_Click(object sender, EventArgs e)        //{        //    //打印预览        //    //PrintPreviewDialog ppd = new PrintPreviewDialog();        //    PrintDocument pd = new PrintDocument();        //    //设置边距        //    Margins margin = new Margins(20, 20, 20, 20);        //    pd.DefaultPageSettings.Margins = margin;        //    ////纸张设置默认        //    //PaperSize pageSize = new PaperSize("First custom size", 800, 600);        //    //pd.DefaultPageSettings.PaperSize = pageSize;        //    //打印事件设置        //    pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);        //    //ppd.Document = pd;        //    //ppd.ShowDialog();        //    try        //    {        //        pd.Print();        //    }        //    catch (Exception ex)        //    {        //    }        //}    }}

打印完了你总知道吧，再打几个空行，再切

我之前写过 小票的打印，
直接是写文本文件的方式，只不是写的对象是打印机的端口，

希望对你的帮助：

C# code        #region Print_CashResult        public static void Print_CashResult(DataTable dt)        {            SafeFileHandle sfh = null;            string instruction = null;            IntPtr ptr = CreateFile(PrintPort, FileAccess.Write, FileShare.Write, 0, FileMode.Open, 0, IntPtr.Zero);            if (ptr.ToInt32() == -1)            {                MessageBox.Show(string.Format("连接打印机：{0} 失败，请检查连接端口是否正确。", PrintPort ));                return;            }            sfh = new SafeFileHandle(ptr, true);            StreamWriter sw = new StreamWriter( new FileStream( sfh, FileAccess.Write), System.Text.Encoding.Default);            StringBuilder sb = new StringBuilder();            DataRow dr = dt.Rows[0];    //一次充值只有1行            sb.AppendLine(string.Format("单据编号:{0}",dr["BillNo"]));            sb.AppendLine(string.Format("{0,-15}{1,23}",ClubName + "(客户联)","充值"));            sb.AppendLine("================================================");            sb.AppendLine(string.Format("{0,-19}{1,18}", "客户编号:" + CustNo, "客户名称:" + CustName));            sb.AppendLine("------------------------------------------------");            sb.AppendLine(string.Format("{0}{1}{2}{3}{4}", "单据编号  ", "充值时间  ", "账户余额 ", "充值金额 ", "  账户金额"));            sb.AppendLine(string.Format("{0,-10}{1,-9:yy-MM-dd}{2,-9}{3,-9}{4,10}", dr["BillNo"], dr["ResultDate"], dr["RemainAccount"].ToString().Replace(".00", ""), dr["ResultMoney"].ToString().Replace(".00", ""), dr["Account"].ToString().Replace(".00", "")));            sb.AppendLine("------------------------------------------------");            sb.AppendLine(string.Format("打印日期:{0:yyyy-MM-dd HH:mm}------操作员:{1,5}",DateTime.Now,dr["Operator"]));            sw.WriteLine(sb);   //第1次 打客户联            instruction = Convert.ToChar(29) + instruction + Convert.ToChar(86) + instruction + Convert.ToChar(66) + instruction + Convert.ToChar(100); //切纸            sw.WriteLine(instruction);  //切纸            sw.WriteLine(sb.Replace("(客户联)","(留底联)"));   //第2次 打(留底联)            sw.WriteLine(instruction);  //切纸            sw.Close();            CloseHandle(ptr);        }        #endregion
