printing more than one page to Windows fax and scan

I have a richTextBox with a long text that i need to send to fax using Windows fax and scan. this process works well if the text doesn't span more than one page, if it does it generates a tiff file that cannot be read

my code looks like:

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            listBox1.Items.Clear();
            
            foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
                listBox1.Items.Add(printer);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            richTextBoxLink1.CreateDocument(printingSystem1);
            richTextBoxLink1.Print(listBox1.SelectedItem.ToString());
        }

        private void button2_Click(object sender, EventArgs e)
        {
            linesPrinted = 0;
            printDialog1.PrinterSettings.PrinterName = listBox1.SelectedItem.ToString();
            printDocument1.Print();
        }

        void doc_EndPrint(object sender, PrintEventArgs e)
        {
           
        }

        void doc_BeginPrint(object sender, PrintEventArgs e)
        {
            linesPrinted = 0;
        }

        private int linesPrinted = 0;

        void doc_PrintPage(object sender, PrintPageEventArgs e)
        {
            int x = e.MarginBounds.Left;
            int y = e.MarginBounds.Top;
            Brush brush = new SolidBrush(richTextBox1.ForeColor);

            while (linesPrinted < richTextBox1.Lines.Length)
            {
                e.Graphics.DrawString(richTextBox1.Lines[linesPrinted++],
                     richTextBox1.Font, brush, x, y);
                y += 15;
                if (y >= e.MarginBounds.Bottom)
                {
                    e.HasMorePages = true;
                    return;
                }
                else
                    e.HasMorePages = false;
            }
            e.Graphics.Flush(System.Drawing.Drawing2D.FlushIntention.Sync);
        }
    }

the form contains a button, a richtextbox and a list box. when running, select the fax (from windows fax and scan - windows 7) and press the button.

if I print to a normal printer or a pdf writer is fine, it only doesn't work with the fax, am I doing something wrong?
