以编程方式“你好世界"ASP.NET MVC 中的默认服务器端打印机 [英] Programmatically "hello world" default SERVER-side printer in ASP.NET MVC

问题描述

我安装了打印机并在 Intranet 服务器上工作，我想以编程方式将hello world"发送到该默认打印机.这似乎是最简单的事情，但我已经用谷歌搜索了几个小时但没有成功.(注意:我正在运行 Windows 7 的部署机器上开发 asp.net mvc)

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)

我试图从 VB 这里翻译一个例子进入 C# 但它说没有安装打印机".

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);
}

我还尝试了 MSDN 中的一个片段 此处 但它说它无法识别打印机名称.

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();
}

推荐答案

在 .NET 中打印hello world"服务器端

Print "hello world" server-side in .NET

1. 共享打印机
2. 创建一个PrintDocument 对象
3. 按名称引用打印机
4. 添加提供内容的方法
5. 打印

代码

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

public void Print()
{
  var doc = new PrintDocument();
  doc.PrinterSettings.PrinterName = "\\deployment-machine-name\share-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);
}
