    Routine Description:
        Enumerates the data types supported by the print processor.

    Arguments:
        pName               => server name
        pPrintProcessorName => print processor name
        Level               => level of data to return (must be 1)
        pDatatypes          => structure array to fill in
        cbBuf               => length of structure array in bytes
        pcbNeeded           => buffer length copied/required
        pcReturned          => number of structures returned

    Return Value:
        TRUE  if successful
        FALSE if failed - caller must use GetLastError for reason
