Paper size in Printing

How to print in WINNT to folder paper, which size isn't
offer in Printing setup dialog. Is any way how  to add a chois custom size of  paper to Printing Setup dialog?

I tried change paper size after calling Print dialog by
following code:

LPDEVMODE devMode = pInfo->m_pPD->GetDevMode();
devMode->dmFields|=DM_PAPERLENGTH|DM_PAPERWIDTH|DM_PAPERSIZE;
devMode->dmPaperSize=0;
devMode->dmPaperLength=myLength();
devMode->dmPaperWidth=myWidth();
CPrintDialog * pPD = pInfo->m_pPD;
CDC *dc= new CDC();
dc->Attach(pPD->m_pd.hDC);
dc->ResetDC(devMode);
long height = dc->GetDeviceCaps(VERTSIZE)  ;

The result is that height is apropriate to A4 paper size, not
to my size.

                       Thank You    Ivan

I'd try this in your winapp.  Call this before you do any printing (eg. in your InitInstance) to set the size you want.  I use this technique for changing the paper orientation to landscape.

void CMyWinApp::SetSize(int width, int length) {
  // Get default printer settings.
  CPrintDialog dlg(false);
  if (GetPrinterDeviceDefaults(&dlg.m_pd)) {
    // Lock memory handle.
    LPDEVMODE pDevMode = (LPDEVMODE)::GlobalLock(m_hDevMode);
    // Change printer settings in here.
    if (pDevMode) {
      pDevMode->dmFields |= DM_PAPERLENGTH|DM_PAPERWIDTH|DM_PAPERSIZE;
      pDevMode->dmPaperSize=0;
      pDevMode->dmPaperLength=length;
      pDevMode->dmPaperWidth=width;
    }
    // Unlock memory handle.
    ::GlobalUnlock(m_hDevMode);
  }
}

The problem isn't where to set the paper size. When I experiment with code written in my question, I was succesful only when I used some paper size, which is offered in print dialog.

For examle code  
devMode->dmFields|=DM_PAPERSIZE;
devMode->dmPaperSize=DM_PAPERQUATRO;
work OK.

So I thing, that place the code in InitInstance isn't solution.
I doubt whether printer driver allowed other paper size, then is offered in print dialog.

The dmPaperSize member of the DEVMODE structure is documented incorrectly. The documentation states that the dmPaperSize member may be set to zero if the length and width of the paper are specified by the dmPaperLength and dmPaperWidth members, respectively. However, the correct value to use for user-defined paper sizes is DMPAPER_USER.

Even if I used DMPAPER_USER, I can't change the paper size.
I tried to do it in OnPreparePrinting. I found  following:

When I used next  code, value of variable heigh isn't appropriate to my  requested paper size, but value is appropriate to A4 . But what is interesting, when I replace the  row
           devMode->dmPaperSize=DMPAPER_USER
by for example
           devMode->dmPaperSize=DMPAPER_QUARTO;
the value heigh is appropriate to choosen paper size, printing is done OK, including pagination.
Whenever I set dmPaperSize to any predefined paper size  result is success.
           Is it  possible that in WINNT is possible to print only on paper size, which are predefined? I can't explain this behavior to myself.
                  Thank's for any advice

BOOL CTReportView::OnPreparePrinting(CPrintInfo* pInfo)
{
      pInfo->m_pPD->m_pd.Flags |= D_HIDEPRINTTOFILE | PD_NOPAGENUMS;
      CPrintDialog * pPD = pInfo->m_pPD;
      BOOL ret = DoPreparePrinting(pInfo);
      LPDEVMODE devMode = pInfo->m_pPD->GetDevMode();
devMode->dmFields|=DM_PAPERLENGTH|DM_PAPERWIDTH|DM_PAPERSIZE;
      devMode->dmPaperSize=DMPAPER_USER;
      devMode->dmPaperLength=1016;
      devMode->dmPaperWidth=2100;

      // DC apropiate to setting made in print dialog
      ::DeleteDC(pPD->m_pd.hDC); // deleting  DC apropiate to setting made in print dialog

      // Creating DC appropriate to my requirement
                 pPD->m_pd.hDC=pPD->CreatePrinterDC();
      dc->Attach(pPD->m_pd.hDC);
      heigh = dc->GetDeviceCaps(VERTSIZE) ;
                return TRUE;
}//CTReportView::OnPreparePrinting

Have you tried setting the paper size in the way I suggested earlier, but with the DMPAPER_USER instead of 0.  ie:

void CMyWinApp::SetSize(int width, int length) {
  // Get default printer settings.
  CPrintDialog dlg(false);
  if (GetPrinterDeviceDefaults(&dlg.m_pd)) {
    // Lock memory handle.
    LPDEVMODE pDevMode = (LPDEVMODE)::GlobalLock(m_hDevMode);
    // Change printer settings in here.
    if (pDevMode) {
      pDevMode->dmFields |= DM_PAPERLENGTH|DM_PAPERWIDTH|DM_PAPERSIZE;
      pDevMode->dmPaperSize=DMPAPER_USER;
      pDevMode->dmPaperLength=length;
      pDevMode->dmPaperWidth=width;
    }
    // Unlock memory handle.
    ::GlobalUnlock(m_hDevMode);
  }
}

And then calling this from your InitInstance (say) to set up the required length.  Does this work?

If it does, then the problem may be in how and when your are making your change.  If it does not work, then it may be some limitation of your printer driver.

I find out, that code you suggest to me is running in  WIN95 but not int WINNT. So that means, that driver in WINNT doesn't support users paper size.

        Thank you for your advices.
