Hi, Mei227 :) .
I am not a teacher, just someone who has been using English language for a long time.
The person who invented block letter printing put thousands of people, (copyists), out of work.
Printers were more independant than the copyists and did not depend on the Crown or the government, as the majority of copyists did.
Printers could say what they wished using printed sheets, not words that the Crown or government would have them write. This eventually led to a more democratic society.
Hope this helps.
