Printing page issue with RichText

The printing works fine, except for the fact that it cuts off my text that did not fit into the page. eg.

TEXT:
abababababababbabababa

PAGE:

-----------------|
PAGE |
|

All that will be printed is this:
abababababababb

How do I set it to automatically "wordwrap" or something to the size of the page that will be printed?

I'm using this code to print my text:

.net Code:

Sub PrintPreview()
        Dim Print_Preview As New PrintPreviewDialog
        Print_Preview.Document = PreparePrintDocument()
        Print_Preview.WindowState = FormWindowState.Maximized
        Print_Preview.ShowDialog()
    End Sub
 
    Private Function PreparePrintDocument() As PrintDocument
        Dim Print_Document As New PrintDocument
        AddHandler Print_Document.PrintPage, AddressOf Print_PrintPage
        Return Print_Document
    End Function
 
    Private Sub Print_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)
        Dim Page As String
        Page = Me.rt.Text
        e.Graphics.DrawString(Page, rt.Font, Brushes.Black, 50, 50)
        e.HasMorePages = False
    End Sub

Have a look at they documentation for DrawString. It has numerous overloads, allowing you to do various things. Also, unless you know for a fact that there won't be enough text to fill the page, you're going to have test the size of the text you're printing to determine how much can fit on the page and only draw that much, saving the rest for the next page.
