Hi all,
I need to find the width of the paper loaded in the user's default printer.
The printer may be a local one or a network printer. The width to be found
should be available even if user specifies paper of custom size.

Thanks in advance!

Try this:

   PRINTDLG pd;
   pd.lStructSize=(DWORD)sizeof(PRINTDLG);
   BOOL bRet=AfxGetApp()->GetPrinterDeviceDefaults(&pd);
   if(bRet)
   {
      // protect memory handle with ::GlobalLock and ::GlobalUnlock
      DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(m_hDevMode);

      // test here pDevMode->dmPaperSize and pDevMode->dmPaperWidth


      ::GlobalUnlock(m_hDevMode);
   }

You need a printer DC from your default printer, and the use GetDeviceCaps:

int width = GetDeviceCaps(hPrtDC,PHYSICALWIDTH) / GetDeviceCaps(hPrtDC,LOGPIXELSX) * 1000;
int height = GetDeviceCaps(hPrtDC,PHYSICALHEIGHT) / GetDeviceCaps(hPrtDC,LOGPIXELSY) * 1000;

Here is a better code I have tested:

CPrintDialog dlg(FALSE);
dlg.GetDefaults();
HDC hPrtDC = dlg.m_pd.hDC;

// Page dimensions in inches
double width = (double)GetDeviceCaps(hPrtDC,PHYSICALWIDTH) / GetDeviceCaps(hPrtDC,LOGPIXELSX);
double height = (double)GetDeviceCaps(hPrtDC,PHYSICALHEIGHT) / GetDeviceCaps(hPrtDC,LOGPIXELSY);

According to MSDN documentation, you must free the dc after using it:

::DeleteDC(m_pd.hDC);
