C#获取打印机列表方法介绍

方法一

第一步：添加引用

using System.Printing;

第二步：代码

public static List<string> GetPrintList()
{
   List<string> lt = new List<string>();
   LocalPrintServer printServer = new LocalPrintServer();
   PrintQueueCollection printQueuesOnLocalServer = printServer.GetPrintQueues(new[] { EnumeratedPrintQueueTypes.Local });
   foreach (PrintQueue printer in printQueuesOnLocalServer)
       lt.Add(printer.Name);
   return lt;
}

方法二

需要引入

System.Drawing.Printing
System.Management

实现

1.获取打印机列表
2.获取默认打印机
3.设置默认打印机

上代码

public class PrinterExample
   {
       /// <summary>
       /// 设置默认打印机
       /// </summary>
       /// <param name="Name"></param>
       /// <returns></returns>
       [DllImport("winspool.drv")]
       public static extern bool SetDefaultPrinter(String Name); //调用win api将指定名称的打印机设置为默认打印机

/// <summary>
       /// 获取默认打印机
       /// </summary>
       /// <returns></returns>
       public static string GetDefaultPrinter()
       {
           PrintDocument print = new PrintDocument();
           string defaultName = print.PrinterSettings.PrinterName;//默认打印机名
           return defaultName;
       }

/// <summary>
       /// 获取本地所有打印机
       /// </summary>
       /// <returns></returns>
       public static List<String> GetLocalPrinters()
       {
           List<String> printer_names = new List<String>();

foreach (String item in PrinterSettings.InstalledPrinters)
           {
               printer_names.Add(item);

}
           return printer_names;
       }

/// <summary>
       /// 获取本地所有打印机 System.Management方式获取
       /// </summary>
       /// <returns></returns>
       public static List<String> GetLocalPrinters2()
       {
           List<String> printer_names = new List<String>();

ManagementObjectCollection queryCollection;
           string _classname = "SELECT * FROM Win32_Printer";

Dictionary<string, ManagementObject> dict = new Dictionary<string, ManagementObject>();
           ManagementObjectSearcher query = new ManagementObjectSearcher(_classname);
           queryCollection = query.Get();

foreach (ManagementObject mo in queryCollection)
           {
               string oldName = mo["Name"].ToString();
               printer_names.Add(oldName);

}
           return printer_names;
       }
   }
