C# winApp printDocument PrintPage สามารถใช้งาน task หรือ thread ในการทำงานได้ไม๊ ครับ

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
         {
             //Loop till all the grid rows not get printed
             if (bFirstPage) printDocumentNewPage(sender, e);
