How many years passed between the invention of printing press and web?

There seems to be a misunderstanding in your question. The web, as in the internet, wasn't invented until very recently compared to the printing press. The printing press was invented by Johannes Gutenberg in around 1440 in Europe, while the modern concept of the World Wide Web (WWW) emerged in the late 20th century, with the first website going live in 1991. Therefore, there are roughly 550 years separating the invention of the printing press and the invention of the web.
