1. The following adds menu pad under "Format", adds the "FontDialog" object, and handler code.
        ...Above the constructor
        // Adding the FontDialog object from the toolbox writes this code
        private System.Windows.Forms.FontDialog dlgFont;

        ...In the InitializeComponent() method
            dlgFont = new System.Windows.Forms.FontDialog();
            // Change default font to match text box
            dlgFont.Font = textBoxEdit.Font;
            // Activate the apply button
            dlgFont.ShowApply = true;
            // Subscribe to the apply event
            dlgFont.Apply += new System.EventHandler(OnApplyFontDialog);

            // miFormatFont menu pad
            miFormatFont.Index = 0;
            miFormatFont.Text = "&Font";
            miFormatFont.Click += new System.EventHandler(miFormatFont_Click);

        ...At the bottom of the code as handler to Color menu pad
        // Launch dialog for font change of text in textbox
        private void miFormatFont_Click(object sender, System.EventArgs e)
        {
            dlgFont.ShowDialog();
        }

        // When apply button is pressed within font dialog
        private void OnApplyFontDialog(object sender, System.EventArgs e)
        {
            textBoxEdit.Font = dlgFont.Font;
        }

        ...Revise two lines of code in this existing method
        private void OnPrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {

            ...Existing code ignored

            <s>//e.Graphics.DrawString(lines[linesPrinted++], new Font("Arial", 10), Brushes.Black, x, y);</s>
            e.Graphics.DrawString(lines[linesPrinted++], textBoxEdit.Font, Brushes.Black, x, y);
            <s>//y += 15;</s>
            y += textBoxEdit.Font.Height;

2. The following adds menu pad under "Format", adds the "ColorDialog" object, and handler code.
        ...Above the constructor
        // Adding the ColorDialog object from the toolbox writes this code
        private System.Windows.Forms.ColorDialog dlgColor;

        ...In the InitializeComponent() method
            dlgColor = new System.Windows.Forms.ColorDialog();

            // miFormatColor menu pad
            miFormatColor.Index = 1;
            miFormatColor.Text = "&Color";
            miFormatColor.Click += new System.EventHandler(miFormatColor_Click);

        ...At the bottom of the code as handler to Color menu pad
        // Launch dialog for color change of text in textbox
        private void miFormatColor_Click(object sender, System.EventArgs e)
        {
            if (dlgColor.ShowDialog() == DialogResult.OK)
                textBoxEdit.ForeColor = dlgColor.Color;
        }

        ...Revise some code in this existing method
        private void OnPrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            ...Existing code ignored

            // Add following lines above the while loop
            Brush pageBrush = Brushes.Black;
            if (e.PageSettings.Color == true)

            ...Existing code ignored

            <s>//e.Graphics.DrawString(lines[linesPrinted++], new Font("Arial", 10), Brushes.Black, x, y);</s>
