Answer 2

Around 1806–07, a Hindu called Babu Ram established a printing machine for the first time, in Devanagari type, at Kidderpore, Calcutta, for publishing Sanskrit books. Thomas Roebuck in The Annals of the College of Fort William[6] talks about the Lord Minto's lecture at Fort William College on 27 February 1808: "A printing press has been established by learned Hindoos, furnished with complete founts of improved Nagree types of different sizes, for the printing of books in the Sunskrit language. This press has been encouraged by the College to undertake an edition of the best Sunskrit Dictionaries, and a compilation of the Sunskrit rules of Grammar... It may be hoped, that the introduction of the art of printing among the Hindoos, which has been thus begun by the institution of a Sunskrit press, will promote the general diffusion of knowledge among this numerous and very ancient people; at the same time that it becomes the means of preserving the classic remains of their literature and sciences."
