There is a code something like this over the internet but I am unable to detect the printer name I am looking for:

DirectorySearcher srch = new DirectorySearcher();
    DirectoryEntry entry = srch.SearchRoot;
    string domain = (string)entry.Properties["DC"][0];

DirectoryEntry DomainEntry = new DirectoryEntry("WinNT://" + domain);

   DomainEntry.Children.SchemaFilter.Add(this.txtSchemaFilter.Text.Trim()); //"UNIQUE"); //computer dn

    foreach(DirectoryEntry machine in DomainEntry.Children)
    {
     string[] Ipaddr = new string[3];
     Ipaddr[0] = machine.Name;

     System.Net.IPHostEntry Tempaddr = null;
     this.Status.Text = "Collecting Information..."+Ipaddr[0];
     try
     {
      Tempaddr = (System.Net.IPHostEntry)Dns.GetHostByName(machine.Name);
     }
     catch(Exception ex)
     {
      System.Windows.Forms.ListViewItem TempItem1 = new ListViewItem(machine.Name);
       this.lstExclude.Items.Add(TempItem1);
       continue;
     }
     System.Net.IPAddress[] TempAd = Tempaddr.AddressList;
     foreach(IPAddress TempA in TempAd)
     {
      Ipaddr[1] = TempA.ToString();
    
      //if(Ipaddr[1].ToString() !="10.25.1.221") {isvalid=false; break;}
      isvalid= true;
      byte[] ab = new byte[6];
      int len = ab.Length;

      // This Function Used to Get The Physical Address
      int r = SendARP( (int) TempA.Address, 0, ab, ref len );
      string mac = BitConverter.ToString( ab, 0, 6 );

      Ipaddr[2] = mac;
 
     } 
      System.Windows.Forms.ListViewItem TempItem = new ListViewItem(Ipaddr);
      this.ListHostIP.Items.Add(TempItem);
  
      
     try
     { 
 

      if(Ipaddr[0]!=null)
      {
       if(( Ipaddr[1]==null) && ( Ipaddr[2]==null))
        sw.Write(" " + Ipaddr[0] +"\r\n");
       else if(( Ipaddr[1]!=null) && ( Ipaddr[2]==null))
        sw.Write(" " + Ipaddr[0]+ "\t\t " + Ipaddr[1]+"\t\t " + "\r\n");
       else
        sw.Write("WorkGroup: " + Ipaddr[0]+ "\t\t " + Ipaddr[1]+"\t\t " + Ipaddr[2] +"\r\n");
      }

     }
     catch{}
      this.Text = "System Info " + this.ListHostIP.Items.Count.ToString();
     
    }

    try{
     sw.Flush();
    }
    catch{}
    try{
     sw.Close();
    }
    catch{}
