我的打印机安装和工作在内部网服务器上，我想以编程方式发送的Hello World到默认打印机。这似乎是最简单的事情，但我一直在Google上搜寻了几个小时，但没有成功。 （注：我开发asp.net mvc的是运行Windows 7的部署机器本身上）

我试着翻译从VB 一个例子这里成C＃，但它说：没有安装打印机。

    VAR TOPMARGIN = e.MarginBounds.Top;
    e.Graphics.DrawString（textToPrint，printFont，Brushes.Black，LEFTMARGIN，TOPMARGIN）;
}
 

我还曾试图从MSDN 一个片段在这里，但它说，它不承认的打印机名称。

解决方案

打印Hello World的服务器端的.NET

共享打印机 创建一个的PrintDocument 对象 通过名称来引用打印机 添加一个方法来提供内容 打印

code

 使用System.Drawing中;
使用System.Drawing.Printing;

公共无效打印（）
{
  VAR DOC =新的PrintDocument（）;
  doc.PrinterSettings.PrinterName =部署，计算机名共享名;
  doc.PrintPage + =新PrintPageEventHandler（ProvideContent）;
  doc.Print（）;
}
公共无效ProvideContent（对象发件人，PrintPageEventArgs E）
{
  e.Graphics.DrawString（
    你好，世界，
    新的字体（宋体，12），
    Brushes.Black，
    e.MarginBounds.Left，
    e.MarginBounds.Top）;
}
 

I have the printer installed and working on an intranet server and I want to programmatically send "hello world" to that default printer. This seems like the simplest thing but I've been googling for a couple hours with no success. (note: I am developing asp.net mvc on the deployment machine itself which is running Windows 7)

I tried to translate an example from VB here into C# but it said "no printers are installed".

public void TestPrint()
{
    var x = new PrintDocument();
    x.PrintPage += new PrintPageEventHandler(PrintPage);
    x.Print();
}
private void PrintPage(Object sender, PrintPageEventArgs e)
{
    var textToPrint = "Hello world";
    var printFont = new Font("Courier New", 12);
    var leftMargin = e.MarginBounds.Left;
    var topMargin = e.MarginBounds.Top;
    e.Graphics.DrawString(textToPrint, printFont, Brushes.Black, leftMargin, topMargin);
}

I had also tried a snippet from MSDN here but it said it did not recognize the printer name.

public void TestPrint(string msg)
{
    var server = new LocalPrintServer();
    var queue = LocalPrintServer.GetDefaultPrintQueue();

    // Call AddJob
    var job = queue.AddJob();

    // Write a Byte buffer to the JobStream and close the stream
    var stream = job.JobStream;
    var buffer = UnicodeEncoding.Unicode.GetBytes(msg);
    stream.Write(buffer, 0, buffer.Length);
    stream.Close();
}

解决方案

Print "hello world" server-side in .NET

Share the printer Create a PrintDocument object Reference the printer by name Add a method to provide content Print

Code

using System.Drawing;
using System.Drawing.Printing;

public void Print()
{
  var doc = new PrintDocument();
  doc.PrinterSettings.PrinterName = "deployment-machine-nameshare-name";
  doc.PrintPage += new PrintPageEventHandler(ProvideContent);
  doc.Print();
}
public void ProvideContent(object sender, PrintPageEventArgs e)
{
  e.Graphics.DrawString(
    "Hello world",
    new Font("Arial", 12),
    Brushes.Black,
    e.MarginBounds.Left,
    e.MarginBounds.Top);
}
