So you want to read a text file and print it, correct?

without opening and reading it.

Hmmm. I don't know how to do that. I can tell you how to open and read it. Which version on Builder are you using?

OK. I don't know which type of BCB (Borland C++ Builder) 6 this comes with (Personal, Pro, or Enterprise) but see if your help file mentions TPrintDialog or TPrinterSetupDialog.

The following code is from Borland C++Builder How-To: The Definitive C++Builder Problem-Solver by John Miano, Tom Cabanski, and Harold Howe. The book is out of print but still has some good info. It looks like the form that this code goes to has some menu options for font and printer set up.

void __fastcall TForm1::FormCreate(TObject *Sender)
{
  //Make sure the font dialog starts with the same font as the memo box
  FontDialog1->Font = mEdit->Font;
  //Make sure the printer starts with the same font as the memo box
  Printer()->Canvas->Font = mEdit->Font;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Exit1Click(TObject *Sender)
{
  Close();
}

void __fastcall TForm1::Font1Click(TObject *Sender)

  //If the user pressed OK on the font dialog
  if (FontDialog1->Execute())
  {
    //Change the font of the memo box
    mEdit->Font = FontDialog1->Font;
    //Change the font of the printer
    Printer()->Canvas->Font = FontDialog1->Font;
  }
}
//---------------------------------------------------------------------------
void __fastcall TForm1::PrinterSetup1Click(TObject *Sender)
{
  //Bring up the print setup dialog box
  PrinterSetupDialog1->Execute();
  //Change the font of the printer just in case user changed
  Printer()->Canvas->Font = FontDialog1->Font;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Print1Click(TObject *Sender)
{
  int Iterations, Copies, LineOnPage, LinesPerPage;
  int StartLine, EndLine;
  int x, y, z, PageNumber;

  LinesPerPage = (Printer()->PageHeight /
    Printer()->Canvas->TextHeight("W"));

  //If the user did not ask for collation
  if (!PrintDialog1->Collate)
  {
    //Loop through all the pages once
    Iterations = 1;
    //Print as many copies of each page as the user requested

        StartLine = ((PageNumber - 1) * LinesPerPage);
        //Calculate the memo line that prints at the bottom of this page
        EndLine = LinesPerPage + ((PageNumber - 1) * LinesPerPage) - 1;

        //Asjust the ending line count for the last page (which may not be full)
        if (EndLine >= mEdit->Lines->Count)
          EndLine = mEdit->Lines->Count;

        //For each memo line that will appear on this page
        for (z = StartLine; z < EndLine; z++)
        {
          //Print out a line
          Printer()->Canvas->TextOut(20,
            Printer()->Canvas->TextHeight(mEdit->Lines->Strings[z]) * LineOnPage,
              mEdit->Lines->Strings[z].c_str());
          //Increment the line count
          LineOnPage++;
        }
      }
      //Required copies of page are printed
      //Increment the page number
      PageNumber++;

  //Close the document
