Routine Description:

Arguments:

    lpJob - Points to a valid JOB structure containing at least a valid
        lpPrinter, and JobId.

    Command - Specifies the operation to perform on the specified Job. A value
        of FALSE indicates that only the elements of the JOB structure are to
        be examined and set.

Return Value:

    TRUE - The operation was successful.

    FALSE/NULL - The operation failed. Extended error status is available
        using GetLastError.
