Lightroom4 and DPP plug-in?
If you set DPP as an 'external editor' in LR, LR will generate a 'Tiff' and export it to DPP. This may or may not be what you are looking to do. If you wish LR to export your RAW file to DPP you need to set up an export 'plug in' in LR called 'export directly' which enable you to open your RAW files directly into DPP.
