How To Print Text In C#

If you want to use MultipadPrintDocument in your own code,it's best to rename 
the class and its constructor to something more appropriate. Then add a variable 
of type XXXPrintDocument to your form and implement the menu items as follows:
 

void OnFilePrint(Object sender,EventArgs e)
{
    PrintDialog pd = new PrintDialog();
    _printdocument.Text = _multipadbox.Text;
    _printdocument.Font = _multipadbox.Font;
    pd.Document = _printdocument;
    pd.ShowDialog();
}

void OnFilePrintPreview(Object sender,EventArgs e)
{
    PrintPreviewDialog ppd = new PrintPreviewDialog();
    _printdocument.Text = _multipadbox.Text;
    _printdocument.Font = _multipadbox.Font;
    ppd.Document = _printdocument;
    ppd.ShowDialog();
}

void OnFilePageSetup(Object sender,EventArgs e)
{
    PageSetupDialog psd = new PageSetupDialog();
    psd.Document = _printdocument;
    psd.ShowDialog();
}
