如何打印文档，在Windows窗体C中创建发票＃

Question

我一直在四处寻找，并且不确定我是否找到了答案。如果这似乎是基本的话，我是新编码所以道歉。 我正在尝试使用Windows窗体中的各种输入生成打印发票。我发现当前代码覆盖了上一行。 我已经包含了打印预览，因为它也显示为覆盖行

    private void PrintPreviewControl()
    {
        Form previewForm = new Form();
    PrintPreviewControl previewControl = new PrintPreviewControl();

    previewControl.Document = printDocument1;
        previewControl.Zoom = 0.5;
        previewControl.Dock = DockStyle.Fill;
        previewForm.Controls.Add(previewControl);
        previewForm.ShowDialog();
        previewForm.Dispose();
    }
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {

            Single vPos = 0; //y-axe
            Single hPos = 0; //x-axe

            //Font
            Font fontMedium = new Font("Arial", 16);
            Font fontLargeBold = new Font("Arial", 20, FontStyle.Bold);
            //Font myFont = new Font();

            //Brush
            Brush brushBlue = new SolidBrush(Color.Blue);
            Brush brushBlack = Brushes.Black;
            Brush myBrush = new SolidBrush(Color.Aqua);

        hPos = 100;
        vPos = 150;
        e.Graphics.DrawString("Name", fontLargeBold, brushBlue, hPos, vPos);
        hPos = 300;
        vPos = 150;
        e.Graphics.DrawString(lbxTitle.Text, fontMedium, brushBlack, hPos, vPos);

        e.Graphics.DrawString(txtName.Text, fontMedium, brushBlack, hPos, vPos);
        hPos = 300;
        vPos = 150;

        hPos = 100;
        vPos = 200;
        e.Graphics.DrawString("Email", fontLargeBold, brushBlue, hPos, vPos);
        hPos = 100;
        vPos = 200;
        e.Graphics.DrawString(txtEmail.Text, fontMedium, brushBlack, hPos, vPos);
