ppd.Document = document;
if (ppd.ShowDialog() == DialogResult.OK) ppd.Document.Print();

PrintFile_Click is called from the Print Menu. This routine first assigns the PrintDialog component to the document being printed. The dialog is shown using ShowDialog so the user can set their print settings and to decide whether to print or not.
