Who was printer of first book in English?

It's difficult to say definitively who printed the *first* book in English, as the earliest printing in England was primarily focused on religious texts in Latin.

However, William Caxton is widely considered to be the first printer of books in English in England. He introduced the printing press to England in 1476 and printed his first book, "The Game and Playe of Chesse," in 1474.

While he printed some works in Latin, he is most famous for his English translations and printing of works like:

* "The Canterbury Tales" (1478)

* "Aesop's Fables" (1484)

* "The Golden Legend" (1483)

So, while the precise title of "first printer of English books" may be contested, William Caxton undoubtedly played a crucial role in establishing printing in English and making literature more accessible to a wider audience.
