There's a bit more to it than this

You have to use OpenPrinter() and fill a DEVMODE structure with printer
details. To print out a graphic I use

   DOCINFO di;
   HDC PrnDC;
   LPDEVMODE devm;
   LONG devModeSize;
   HANDLE hPrinter;
   char PDevice[100], PDriver[100], PPort[100];

  if(OpenPrinter((LPTSTR)PDevice,phP,NULL))
   {
    devModeSize=DocumentProperties(NULL,hPrinter,
(LPSTR)PDevice,NULL,NULL,0);
  if(devModeSize!=0)
      {
       devm=(DEVMODE*) new char[devModeSize];
       DocumentProperties(NULL,hPrinter,NULL,devm,NULL,DM_OUT_BUFFER);
         if(!flPort)  // flag for landscape
     {
          devm->dmFields|=DM_ORIENTATION;
      devm->dmOrientation=DMORIENT_LANDSCAPE;
     }
     devm->dmFields|=DM_PAPERSIZE;
         devm->dmFields|=DM_PRINTQUALITY;
         devm->dmFields|=DM_YRESOLUTION;
         devm->dmPaperSize=DMPAPER_A4;
         devm->dmPrintQuality=300;
         devm->dmYResolution=300;

     memset(&di,0,sizeof(DOCINFO));
     di.cbSize = sizeof(DOCINFO);
     PrnDC= CreateDC(PDriver, PDevice, NULL, devm);
       }

then you can do

       if(StartDoc(PrnDC,&di)!=SP_ERROR)
      {
                  StartPage(PrnDC);
                  BitBlt(PrnDC,Xfact,Yfact,XP,YP,*drw->DCP,0,0,SRCCOPY);
                  EndPage(PrnDC);
                  EndDoc(PrnDC);
      }

Don't forget to cleanup on exit
