When does the father's financial support for his daughter cease to be obligatory, and is an employed, unmarried daughter required to financially support her parents?

The financial support of an unmarried daughter is obligatory upon her father. Her financial support from him ceases upon her marriage or if she has an income sufficient for her needs. The father is not permitted to compel her to work as long as he is capable of providing for her. As for a married woman, her financial support is incumbent upon her husband in exchange for conjugal enjoyment, and her financial support ceases due to her defiance (nushooz), not due to her wealth.
