Can anyone tell me how to get a list of all printers on a network?
I have tried using WMI but the following code only gives me a list of local printers

here is the code that i tried.
//--set the scope of this search to the local machine
              ManagementScope scope = new ManagementScope(@"\root\cimv2");

              //--connect to the machine
              scope.Connect();

              //--query for the ManagementObjectSearcher to get all printer
              SelectQuery selectQuery1 = new SelectQuery();
              selectQuery1.QueryString = "Select * from win32_Printer";
              ManagementObjectSearcher obj = new ManagementObjectSearcher(scope,  selectQuery1);
              ManagementObjectCollection printers = obj.Get();

               //--now loop through each printer instance returned
                  foreach (ManagementObject printer in printers)
                  {
                      //--first make sure that there is a printer
                      if (printer != null)
                      {
                          str = printer["Name"].ToString().ToLower();

                          //--check if it matches the name provided
                          if (str.ToUpper().Equals("MyPrinterName".ToUpper()))
                          {
                              //--since we found a match check it's status
                              if  (printer["WorkOffline"].ToString().ToLower().Equals("true") || printer["PrinterStatus"].Equals(7))
                              {
                                  //--it's offline
                                  online = false;
                              }
                              else
                              {
                                  //--it's online
                                  online = true;
                              }
                          }
                      }
                      else
                      {
                          throw new Exception("No printers were found");
                      }

There's no one method that's going to get all printers. It depends on how your printers are connected to the network. Are they all available through a single print server? Are they in ActiveDirectory? Are they just sitting around with IP addresses so any client install their own drivers and print direct IP to them??

First, you're replying to a post that's 3 YEARS old. Don't. Create your own thread with the full details of your question.

Second, I have no idea what you're talking about.
