Explain importance of the printing press over scribal system

History paper
Please view the film: “Leonardo DaVinci The Man Who Wanted To Know Everything” (Feel free to skip the re-creation of his parachute and tank); Available at: http://www.youtube.com/watch?v=Rog5i2n1QVs
And read: Pamela O. Long, “Power, Patronage, and the Authorship of Ars: From Mechanical Know-How to Mechanical Knowledge in the Last Scribal Age,” Isis , Vol. 88, No. 1 (Mar., 1997), pp. 1-41. Also, read the Ch.1 of Misa.
Then discuss: In her essay, Long examines many topics mentioned in lecture and in Misa’s chapter (patronage, Alberti, Da Vinci and DiGiorgio etc). She focus on several aspects of this history: 1) the importance of the printing press over the scribal system, 2) the power relationship between artisans and the various elite princes, and others.
Please discuss both:
A) Choose one of the authors she covers and discuss how her discussion of this person’s book(s) relates to these topics; and
B) Based on the film Leonardo DaVinci discuss how he fits into Long’s discussion of Prince Practitioners?
Use specific examples from Misa, Long, the Film and the lecture as needed to support your argument. Cite these so I can tell where you are getting your information, for example: (Misa, P. XX), (Long, pp. xx-xx), and/or refer to a specific scene in the film or slide in the lecture.
This paper need to be 350-450 words.
