Before Gutenberg's invention woodblock printing was used; this took a lot longer as the lettering was carved by hand. It was also extremely costly as the wood would have a short life span, so the lettering would have to be reproduced on a large scale.
All seemed to be going well, until 1455 when Fust sued Gutenberg winning possession of all the equipment and the almost completed version of the Bible -- this was completed in 1456. One year after the production of the Bible, Fust and former assistant to Gutenberg, Peter Schoffer, published the Mainz Psalter which featured red and blue text; this Psalter was also the first book to have the printer's trademark and imprint along with the date of publication.
At this point it is clear to see the impact that Gutenberg's invention had on the advancement for printing. People were now able to read the Bible and not only saw publications as a reminder of the past, but also as a sign for the future.
Even though Gutenberg had lost his invention to Fust, he was not finished. He created the new printer's outfit which was a set of small types with round, cursive handwriting an invention which really took off after Gutenberg's death in 1468. One of the most influential printers was a man called William Caxton. He was an Englishman who was the first to bring the print press to England (1476) and was arguably the best printer of his day. It can be said that Caxton was the important figure for printing in England and was therefore instrumental in getting English scholars heard around the world.
The print press houses were so common that by 1499 more than 2500 European cities had one; also by this time 15 million books had been produced, which is a staggering amount. Obviously, the more books that were produced, the cheaper they became. And this, in turn, meant that wider groups of the public were able to enjoy them.
