}

 打印机寻找:

using System;
using System.Collections.Generic;
using System.Drawing.Printing;
using System.Web;

public class Printer
{
    private static PrintDocument fPrintDocument = new PrintDocument();
    /// <summary>
    /// 获取本机默认打印机名称 
    /// </summary>
    public static string DefaultPrinter
    {
        get
        {
            return fPrintDocument.PrinterSettings.PrinterName;
        }
    }
    /// <summary>
    /// 获取本机的打印机列表。列表中的第一项就是默认打印机。
    /// </summary>
    private static List<string> GetLocalPrinters()
    {
        List<string> fPrinters = new List<string>();
        fPrinters.Add(DefaultPrinter);
        foreach (string fPrinterName in PrinterSettings.InstalledPrinters)
        {
            if (!fPrinters.Contains(fPrinterName))
                fPrinters.Add(fPrinterName);
        }
        return fPrinters;
    }

    //检查本地打印机中是否有Printer打印机
    public static bool VerifyPrinter(string Printer)
    {
        return GetLocalPrinters().Contains(Printer);
    }
}

 服务配置:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <identity impersonate="true" userName="administrator" password="123@abc"/>
    <authentication mode="Windows"/>
    <compilation debug="true"/>
