How to print postscript file in dialog based application?

I have a postscript file need to be printed in a dialog application, I want to have print button
in the dialog window, when "Print" button  is clicked,
print dialog starts, so user can choose the printer, font,
pages.... , then it prints the postscript file stored at my local directory. I don't need to view this file.

Thanks.

What is your exact problem? What are the steps where you're stuck?
Or do you want us to do all the programming work instead of you?

I have the following code, but I couldn't make it work.

      // Print the doc.
      CPrintDialog dlgPrint (FALSE, PD_ALLPAGES, this);

      if (dlgPrint.DoModal() == IDOK) {
      CDC dcPrint;
                  dcPrint.Attach (dlgPrint.GetPrinterDC ());

                  // Create and fill a DOCINFO structure
                  DOCINFO myPrintJob;
                  myPrintJob.cbSize = sizeof(m_sigImageLen);
                  myPrintJob.lpszDocName = tmpDocFile;
                  myPrintJob.lpszOutput = NULL;
                  myPrintJob.lpszDatatype = NULL;
                  myPrintJob.fwType = NULL;

                  // Start to print file.
                  if (dcPrint.StartDoc(&myPrintJob) >= 0) {
                        dcPrint.StartPage();
                  //      dcPrint.TextOut(0,0,"My Samll Print Job");
                        dcPrint.EndPage();
                        dcPrint.EndDoc();
                  }
                  dcPrint.DeleteDC();
            }

myPrintJob.lpszDocName is simply the document/job name you'll see when you open the printer properties and check that jobs waiting for printing.

Assuming your postscript file is understood by your printer, you only have to send it to the printer as raw data.
You won't need to create a DC, neither will you have to use StartDoc.

bool SendFileToPrinter (const char* fnm)
{
      char                        buffer[8192];
      HANDLE                        hFile, hPrinter;
      DWORD                        numRead, numWritten;
      bool                        success;
      DOC_INFO_1                  docInfo;
      char                        dataType[16] = "RAW";     // MUST be uppercase, otherwise won't work on Win9x.
      char*                        p;


      hFile = CreateFile (fnm, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
      if (hFile == INVALID_HANDLE_VALUE)
            return (false);

      if (!OpenPrinter (defPrnName, &hPrinter, NULL)) {
            CloseHandle (hFile);
            return (false);
      }

      ZeroMemory (&docInfo, sizeof (docInfo));
      docInfo.pDocName = fnm;
      docInfo.pDatatype = dataType;
      success = (StartDocPrinter (hPrinter, 1, (LPBYTE) &docInfo) != 0);

      for ( ; success; ) {
            success = ReadFile (hFile, buffer, sizeof (buffer), &numRead, NULL);
            if (!success || numRead == 0)
                  break;
            success = WritePrinter (hPrinter, buffer, numRead, &numWritten);
            if (numRead != numWritten)
                  success = false;
      }

      EndDocPrinter (hPrinter);
      ClosePrinter (hPrinter);
      CloseHandle (hFile);

      return (success);
}

Do I need to add some header file?, it complains function:
OpenPrinter(),
StartDocPrinter(),
WritePrinter(),
EndDocPrinter(),
ClosePrinter(),
are undeclared identifiers.

Thanks.

<windows.h>
But I don't understand. If DOCINFO is defnied, these functions also should be defined.

Right now I hard code the name of printer, it works well.
Thanks a lot.  

BTW  if it doesn't take your much time,
do you know how to get name of the default printer for this function
OpenPrinter (defPrnName, &hPrinter, NULL)) ?

Thanks.

Ask another question (for only a few points if you don't have much) and I'll tell you.
(Just that if someone searches through question titles, should find the solution for that question.)
