Original sentence: It was invented in Germany by the goldsmith and  printer Johannes Gutenberg in the 1440s, though similar presses had been developed in Korea several hundred years earlier.Movable type, which allowed individual characters to be arranged to form words and which is a separate invention from the printing press, was invented also in Germany by Gutenberg in the 1450s, and in China by Bi Sheng between 1041 to 1048.The earliest woodblocks used for printing in Europe, in the fourteenth century, were remarkably similar to Chinese woodblocks, leading some scholars to hypothesize a connection, although dfirect evidence remains lacking: "the process of printing them must have been copied from ancient Chinese specimens, brought from that country by some early travelers, whose names have not been handed down to our times" (Robert Curzon, 1810-1873)
