小票打印

[luluyy]

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

namespace WindowsApplication1

        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 <= 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);

        //    }
        //    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：

        #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

进来学习下，楼主长的像以前的同事

[luluyy]

自己顶一下

[luluyy]

是COM口打印的,总是的关键有两点
1、切纸(切纸命令)
2、打印对齐时对不齐 我用的代表例似于(上面的那种)：

打印如果只有一行的话调整好了，但是如果是多行的话，商品名称汉字有的多有的少就调不齐了，想过补空格
但是得计算有点费劲，请问有简单的办法没有？
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"]));

3、打印的时候速度非常慢，打一行停一行 有点受不了啊
