Which affected gutenberg's printing press most directly have on the general population of Europe

The most direct effect of Gutenberg's printing press on the general population of Europe was an increase in access to information and knowledge. Prior to the invention of the printing press, books were extremely expensive and only available to the wealthy or in large public institutions like churches and universities. With the printing press, books became more affordable and widespread, allowing more people to access and engage with a wide range of ideas, news, and literature.

This increase in access to knowledge had wide-ranging effects on European society. It facilitated the spread of new ideas, scientific discoveries, and religious reformations. It also helped to standardize language and communication as printed materials became more widely available. Overall, the printing press played a crucial role in ushering in the period of intellectual and cultural flourishing known as the Renaissance in Europe.
