我有一个问题，在这个程序中我Map了一个标签网络打印机，所以我想知道我连接到了哪台打印机，这是我的函数。有什么函数可以让我知道我连接的打印机在哪里吗？
例如“您已连接到打印机“DESKTOP01”

public void impressora(string computador)
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();
    System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

    startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
    startInfo.FileName = "cmd.exe";
    startInfo.Arguments = $@"/c net use lpt1: /delete & net use lpt1: \\{computador}\zpl";
    process.StartInfo = startInfo;
    process. Start();
}

winforms

public void checkimpressora()
    {
        System.Diagnostics.Process process = new System.Diagnostics.Process();
        process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        process.StartInfo.FileName = "cmd.exe";
        process.StartInfo.Arguments = $@"/c net use lpt1:";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.CreateNoWindow = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.RedirectStandardInput = true;
        process.Start();
        string q = "";
        q += process.StandardOutput.ReadToEnd();
        string m = q.Replace("Local name        LPT1", " ").Replace("Resource type     Print", " ").Replace("Status            OK", " ").Replace("# Opens           0", "").Replace("# Connections     1", " ").Replace("The command completed successfully.", " ").Replace(@"Remote name       \\", " ").Replace(@"\zpl", " ").Replace(" ", "").Replace("\r\n", "");
        if (m != "")
        {
            if (m == "BRMAOPR094")
            {
                resetallbuttons();
                changecolor(pcm);
            }
        } 
    }
