Please how can I get the right LPITEMIDLIST to use for IShellLink::SetIDList?

I tried

HRESULT hr = S_OK;
ULONG celtFetched;
LPITEMIDLIST pidlItems = NULL;
LPITEMIDLIST netItemIdLst = NULL;
IShellFolder* pPrinterFolder = NULL;
IEnumIDList* pEnumIds = NULL;
IMalloc* pMalloc = NULL;
IShellFolder* pDesktopFolder = NULL;
CoInitializeEx( NULL, 0 );
hr = SHGetMalloc( &pMalloc );
hr = SHGetDesktopFolder( &pDesktopFolder );
hr = SHGetSpecialFolderLocation( NULL, CSIDL_PRINTERS, &netItemIdLst );
hr = pDesktopFolder->BindToObject( netItemIdLst, NULL, IID_IShellFolder, (void **)&pPrinterFolder );

if ( SUCCEEDED( hr ) )
{
    hr = pPrinterFolder->EnumObjects( NULL, SHCONTF_NONFOLDERS, &pEnumIds );
    if ( SUCCEEDED( hr ) )
    {
        STRRET strDisplayName;
        while ( ( hr = pEnumIds->Next( 1, &pidlItems, &celtFetched ) ) == S_OK && celtFetched > 0 )
        {
            hr = pPrinterFolder->GetDisplayNameOf( pidlItems, SHGDN_NORMAL, &strDisplayName );
            if ( SUCCEEDED( hr ) )
            {
                // used pidlItems for the IShellLink::SetIDList
            }
         }
      }
}

But this result in a blank shortcut (i.e. the shortcut wasn't pointing to anywhere).

EDIT:
Just learnt now that the pidlItems gotten from the enumeration is relative but SetIDList require an absolute LPITEMIDLIST. How can pidlItems be turned to absolute.
