Are toy story and disney princess dolls made by the same manufacturer?

The available information specifically discusses the fictional character Buzz Lightyear from the Toy Story franchise but does not identify any manufacturer of the Toy Story dolls. Likewise, there is no provided source that names the manufacturer of Disney Princess dolls. Because the evidence does not mention either manufacturer, we cannot conclude that the two lines of dolls share a production company. Without additional data, the question remains unanswered.
