    public partial class Form1 : Form
    {

        private void listAllPrinters()
        {
            foreach (var item in PrinterSettings.InstalledPrinters)
            {    
                this.listBox1.Items.Add(item.ToString());
            }
        }

        private void listBox1_SelectedValueChanged(object sender, EventArgs e)

        public Form1()
        {
            InitializeComponent();
            listAllPrinters();
        }
    }

    public static class myPrinters
