如何实现服务器打印WEB上传的文档（ASP.NET C#）

我想实现用户通过asp.net网站上传文档到服务器，然后由连接在服务器上的打印机打印用户上传的文档，文件上传不是问题，关键是打印，希望高手能指点下如何用asp.net实现在服务器端的打印。
服务器和打印机都是在公司内部的。

你的想法很有才。

一服务器托管在电信机房(国外?)，你在大陆访问该站点，现要求打印某文档，要求的结果是：让托管在国外的服务器连接的打印机打印文档。

之后让机房管理人员航空快递到你家？

这是不切实际的要求，，，

winform 可以这样写：
===========================

using System;
using System.IO;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

public class PrintingExample
{
private Font printFont;
private StreamReader streamToPrint;
static string filePath;

public PrintingExample()
{
Printing();
}

// The PrintPage event is raised for each page to be printed.
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
String line=null;

// Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height /
printFont.GetHeight(ev.Graphics) ;

// Iterate over the file, printing each line.
while (count < linesPerPage &&
((line=streamToPrint.ReadLine()) != null))
{
yPos = topMargin + (count * printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString (line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}

// If more lines exist, print another page.
if (line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}

// Print the file.
public void Printing()
{
try
{
streamToPrint = new StreamReader (filePath);
try
{
printFont = new Font("Arial", 10);
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
// Print the document.
pd.Print();
}
finally
{
streamToPrint.Close() ;
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

// This is the main entry point for the application.
public static void Main(string[] args)
{
string sampleName = Environment.GetCommandLineArgs()[0];
if(args.Length != 1)
{
Console.WriteLine("Usage: " + sampleName +" <file path>");
return;
}
filePath = args[0];
new PrintingExample();
}
}
