C# winform打印总结 z

http://blog.csdn.net/jing_xin/article/details/41444063

针对BEIYANG收据打印机 BTP-R580测试通过。

操作说明：http://www.docin.com/p-395110672.html

1、一般的打印

static Font printFont; //打印使用的字体
        public static void PrintEventPage(object sender, PrintPageEventArgs e)
        {

float yPos = 0;
            int count = 0;
            float leftMargin = e.MarginBounds.Left;
            float topMargin = e.MarginBounds.Top;
            //string line = null;
            //string subs = " ";
            string context = null;

//打印字体
            printFont = new Font("宋体", 14F, FontStyle.Bold | FontStyle.Underline);
            //打印内容

context = "收银小票";
            //打印的位置
            yPos = topMargin + (count * printFont.GetHeight(e.Graphics));
            e.Graphics.DrawString(context, printFont, Brushes.Black,
            50, 10, new StringFormat());
            //换行
            count++;

e.HasMorePages = false;
        }

调用处：

System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
            System.Drawing.Printing.PrintDocument docToPrint = new System.Drawing.Printing.PrintDocument();
            docToPrint.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(PrintEventPage);

PrintDialog1.AllowSomePages = true;
            PrintDialog1.ShowHelp = true;

PrintDialog1.Document = docToPrint;//把PrintDialog的Document属性设为上面配置好的PrintDocument的实例
            PrintController printController = new StandardPrintController();
            docToPrint.PrintController = printController;

DialogResult result = PrintDialog1.ShowDialog();//调用PrintDialog的ShowDialog函数显示打印对话框

//If the result is OK then print the document.
            if (result == DialogResult.OK)
            {
                docToPrint.Print();//开始打印
            }

效果：直接调出设置打印机的窗口。

2、USB打印

思路：
1、先找到USB 打印机。SetupDiGetClassDevs、SetupDiEnumDeviceInfo、SetupDiGetDeviceRegistryProperty，找到“USB 支持设备”；
2、然后就是老路，获得该USB打印机的路径，SetupDiEnumDeviceInterfaces、SetupDiGetInterfaceDeviceDetail，获得路径。（SetupDiGetClassDevs不用了，因为1中已经获得句柄集）
3、再根据路径CreateFile，后面的内容网上一搜一大堆。

步骤：
1、CreateFile
2、SetupComm
3、SetCommTimeouts
4、GetCommState
5、SetCommState
6、PurgeComm
7、WriteFile

不知道是不是绕远路了，呵呵。

USB下直接用程序访问不太方便，于是利用下面这个连接里的方法进行LPT并口转换：

然后就可以连接上打印机了。

打印输出并切纸操作：

第一点：

const uint GENERIC_READ =0x80000000;
        const uint GENERIC_WRITE = 0x40000000;     
        const int OPEN_EXISTING = 3;
        private FileStream fs=null;
        IntPtr iHandle;
        [DllImport("kernel32.dll")]
        public static extern IntPtr CreateFileA(string lpFileName, uint
dwDesiredAccess, int dwShareMode, int lpSecurityAttributes, int
dwCreationDisposition, int dwFlagsAndAttributes, int hTemplateFile);

[DllImport("kernel32.dll")]
        private static extern bool WriteFile(
        int hFile,
        byte[] lpBuffer,
        int nNumberOfBytesToWrite,
        ref   int lpNumberOfBytesWritten,
        ref   int i
        );

[DllImport("kernel32.dll")]
        private static extern bool CloseHandle(IntPtr hObject);

第二点：

protected void imageButton1_Click(object sender, ImageClickEventArgs e)
        {
          
            ShopCart mycart = CartCtroller.GetCart();         
           iHandle = CreateFileA("LPT1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, 0, 0);
           if (iHandle.ToInt32() == -1)
           {
               Jscript.AjaxRunJs(this.Page, "alert(‘没有连接打印机或者打印机端口不是LPT1！‘)");
               return;
           }
           else
           {             
               fs = new FileStream(iHandle, FileAccess.ReadWrite);
             
               //for (int i = 0; i < 5; i++)
               //{
               //    fs.WriteByte(0x0A); //走纸(忘记了可能是这个)
               //}
               //StreamReader sr = new StreamReader(fs);   //读数据;  
               //StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);  //些数据;  
            
               if (mycart.Count == 0)
               {
                   Jscript.AjaxRunJs(this.Page, "alert(‘请先购买产品！‘)");
                   return;
               }

byte[] buf = new byte[500];
               char ESC = (char)(27);
               char GS =
(char)(29);                                                                                                                 
               char LF = (char)(10);

//读出数据
               StringBuilder SEND = new StringBuilder();
               //SEND.Append(LF.ToString());    
               char c1 = (char)60;
               char c2 = (char)0;
               SEND.Append(GS.ToString() + "L" + c1.ToString() + c2.ToString());
               SEND.Append(ESC + "D" + Convert.ToChar(25) + Convert.ToChar(30) + Convert.ToChar(0));
               string dt = DateTime.Now.ToString();
               string mingcheng = "产品名称:";
               string miaoshu = "产品描述:";
               string shuliang = "购买数量:";
               string zhi = "支";
               SEND.Append(LF.ToString());   
               SEND.Append("欢 迎 光 临 - 上海金福");
               SEND.Append("\r\n");
               SEND.Append("-------------------------------");
               SEND.Append(LF.ToString());
               SEND.Append("购买时间："+dt);
               SEND.Append("\r\n");
               SEND.Append("-------------------------------");
               SEND.Append(LF.ToString());
               SEND.Append(LF.ToString());
               for (int i = 0; i < mycart.Count; i++)
               {
                   modelArrayProduct temp = (modelArrayProduct)mycart[i];                
                   SEND.Append(mingcheng + temp.T_name);
                   SEND.Append("\r\n");
                   SEND.Append(miaoshu +   temp.T_miaoshu);
                   SEND.Append("\r\n");  
                   SEND.Append(shuliang + temp.T_shuliang.ToString() + zhi);
                   SEND.Append("\r\n");  
                   SEND.Append("-------------------------------");
                   SEND.Append(LF.ToString());                   
               }

//走纸
               SEND.Append(LF.ToString());
               SEND.Append(LF.ToString());             
               SEND.Append(LF.ToString());
               SEND.Append(LF.ToString());
               SEND.Append(GS + "V" + Convert.ToChar(1));
             
                //字符类型转换
               Encoding utf8 = Encoding.GetEncoding(65001);
               Encoding gb2312 = Encoding.GetEncoding("gb2312");//Encoding.Default ,936
               byte[] tempa = utf8.GetBytes(SEND.ToString());

buf = Encoding.Convert(utf8, gb2312, tempa);
                                       
              fs.Write(buf, 0, buf.Length);
                          fs.Close();                       
           }
                 CloseHandle(iHandle);

}

C#执行批处理命令

using System.Diagnostics ;

using System.IO;

private void btnRun_Click(object sender, EventArgs e)
        {
            txtResult.Text = "";
            processCommand("Ping.exe", this.txtAddress.Text);
            processCommand("Ping.exe", this.txtAddress.Text);
        }

public void processCommand(string commandName, string argument)
        {
            ProcessStartInfo start = new ProcessStartInfo(commandName);//设置运行的命令行文件问ping.exe文件，这个文件系统会自己找到
            //如果是其它exe文件，则有可能需要指定详细路径，如运行winRar.exe
            start.WorkingDirectory = "d:\\360Downloads\\";
            start.Arguments = argument;//设置命令参数
            start.CreateNoWindow = true;//不显示dos命令行窗口
            start.RedirectStandardOutput = true;//
            start.RedirectStandardInput = true;//
            start.UseShellExecute = false;//是否指定操作系统外壳进程启动程序
            txtResult.AppendText(start.WorkingDirectory  + "\n");
            Process p = Process.Start(start);
            StreamReader reader = p.StandardOutput;//截取输出流
            string line = reader.ReadLine();//每次读取一行
            while (!reader.EndOfStream)
            {
                txtResult.AppendText(line + "\n");
                line = reader.ReadLine();
            }
            p.WaitForExit();//等待程序执行完退出进程
            p.Close();//关闭进程
            reader.Close();//关闭流
        }

以上均测试成功。
