    {
        fileName = ofd.FileName;

        var application = new Microsoft.Office.Interop.Word.Application();
        //var document = application.Documents.Open(@"D:\ICT.docx");
        var document = application.Documents.Open(@fileName);
    }
}


private void btnPrint_Click(object sender, EventArgs e)
{
    PrintDialog printDlg = new PrintDialog();
    PrintDocument printDoc = new PrintDocument();
    printDoc.DocumentName = "fileName";
    printDlg.Document = printDoc;
    printDlg.AllowSelection = true;
    printDlg.AllowSomePages = true;
    //Call ShowDialog
    if (printDlg.ShowDialog() == DialogResult.OK)
        printDoc.Print();
}

you need to hadle PrintPage event

Try This:

   String content="";
   private void btnUpload_Click(object sender, EventArgs e)
    {
        string fileName;
        // Show the dialog and get result.
        OpenFileDialog ofd = new OpenFileDialog();
        DialogResult result = openFileDialog1.ShowDialog();
        if (result == DialogResult.OK) // Test result.
        {
            fileName = ofd.FileName;

            var application = new Microsoft.Office.Interop.Word.Application();
            //var document = application.Documents.Open(@"D:\ICT.docx");
             //read all text into content
            content=System.IO.File.ReadAllText(fileName);
            //var document = application.Documents.Open(@fileName);
        }
    }
 private void btnPrint_Click(object sender, EventArgs e)
    {
        PrintDialog printDlg = new PrintDialog();
        PrintDocument printDoc = new PrintDocument();
        printDoc.DocumentName = "fileName";
        printDlg.Document = printDoc;
        printDlg.AllowSelection = true;
        printDlg.AllowSomePages = true;
        //Call ShowDialog
        if (printDlg.ShowDialog() == DialogResult.OK)
        {
             printDoc.PrintPage += new PrintPageEventHandler(pd_PrintPage);            
             printDoc.Print(); 
        }
    }
 private void pd_PrintPage(object sender, PrintPageEventArgs ev)
 {
   ev.Graphics.DrawString(content,printFont , Brushes.Black,
                   ev.MarginBounds.Left, 0, new StringFormat());
 }

If the file I want to print is a PDF and has graphics like tables, formatted text, an image, how can that be drawn on the print page? I have tried searching for this a lot on google, no solution. — D J, Oct 01 '21 at 14:55
