问题描述

我想在客户端计算机上找到或不连接打印机，

为此我写了代码为

Hi,
I want to find wheather printer is connected or not in client computer,
for this i have written code as

ManagementScope scope = new ManagementScope("\\root\\cimv2");

              scope.Connect();

              // Select Printers from WMI Object Collections

              ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Printer");

              string printerName = "";

              foreach (ManagementObject printer in searcher.Get())
              {

                  printerName = printer["Name"].ToString().ToLower();


                  if (printerName.Contains("citizen"))
                  {

                      // Console.WriteLine("Printer = " + printer["Name"]);

                      if (printer["WorkOffline"].ToString().ToLower().Equals("true"))
                      {

                          // printer is offline by user

                          // Console.WriteLine("Your Plug-N-Play printer is not connected.");

                      }

                      else
                      {

                          // printer is not offline

                          Console.WriteLine("Your Plug-N-Play printer is connected.");

                      }
                  }
                  else
                  {



                  }

              }

上面的代码给出了我托管代码的服务器的打印机状态，但是我想要客户端pc的打印机状态。

推荐答案

看一下打印机[Local]属性。



如果是真，则是本地打印机，如果不是网络打印机。

Take a look at the printer["Local"] property.

If it is True then is a Local printer, if not is a network printer.
