You must fill the devmode with desired paper sizes on calls to PrintDlg() or CreateDC(). I think there's no way to modify devmode after this.

In case if you are printing in RAW (TEXT) mode , you can pass in the devmode to OpenPrinter() and proceed to StartDocPrinter -> StartPagePrinter

Wonder why you wish to change page sizes in the middle of printing?

To change DEVMODE settings during a print job (such as different paper bin, paper size, etc), you need to recreate the DC, passing a different DEVMODE struct. If using MFC, below is a snippet that may give you some ideas:

memcpy(pNewDevMode,pCurDevMode,pCurDevMode->dmSize+pCurDevMode->dmDriverExtra);
pNewDevMode->dmFields      = pDevMode->dmFields;
pNewDevMode->dmOrientation = pDevMode->dmOrientation;
pNewDevMode->dmPaperSize   = pDevMode->dmPaperSize;
pNewDevMode->dmPaperLength = pDevMode->dmPaperLength;
pNewDevMode->dmPaperWidth  = pDevMode->dmPaperWidth;
pNewDevMode->dmScale       = pDevMode->dmScale;
pNewDevMode->dmCopies      = pInfo->m_pPD->GetCopies();
pNewDevMode->dmDefaultSource = pDevMode->dmDefaultSource;
CString cDevice = pInfo->m_pPD->GetDeviceName();
CString cDriver = pInfo->m_pPD->GetDriverName();
CString cPort   = pInfo->m_pPD->GetPortName();
HDC hDC = ::CreateDC((LPCSTR)((const char *)cDriver),
                     (LPCSTR)((const char *)cDevice),
                     (LPCSTR)((const char *)cPort),
                     <big>pNewDevMode</big>);
if (hDC)
  {
    pDC->EndDoc();
    HDC hOldDC = pDC->Detach();
    if (hOldDC)
      ::DeleteDC(hOldDC);
    pDC->Attach(hDC);
    pDC->SetAbortProc(PrintAbortProc);
    DOCINFO docInfo;
    ZeroMemory(&docInfo, sizeof(DOCINFO));
    docInfo.cbSize = sizeof(DOCINFO);
    char caName[31];
    strcpy(caName,((const char *)pDoc->GetTitle().Left(30)));
    docInfo.lpszDocName = (LPCSTR)caName;
    docInfo.lpszOutput = NULL;
    if (pDC->StartDoc(&docInfo) == SP_ERROR)
