Before this machine, every single book had to be copied out by hand, which took forever and cost a lot of money.
The printing press let people stamp ink onto page after page quickly using carved or arranged letters, instead of copying every word by hand. This meant one worker could produce dozens or hundreds of identical books in the time it used to take a scribe to finish just one copy.
An umbrella keeps rain off people and a trampoline is for bouncing, neither has anything to do with making copies of writing, so they cannot be the invention described.
Because books became cheap and common after the printing press spread, far more people learned to read, which helped new ideas travel faster across entire countries than ever before.
