Printing, as a technology for creating duplicate images (eg, with wood blocks), was in use at least a millenium prior to Gutenberg in many societies, including parts of late Rome. Moveable type came much later, and it was Gutenberg's incorporation of this with a whole slew of engineering improvements that led to the printing revolution in Europe.

Perhaps I should have done some research before opening my fat mouth ... but duplicate images only or was it extended to duplicate "written" works?

Ex post facto lots of this sort of thing (block printing images -> movable type) seem pretty straight forward, doesn't it.

I think one of the hallmarks of any truly revolutionary technology is the ease and speed with which it spreads, becomes assimilated, and soon seems 'obvious' to those who were born after its adoption. The wheel being the archetypal example.

I'm no expert on printing presses, but the Wikipedia page on Moveable Type has some good material, including the suggestion that Gutenberg's most important innovation was a greatly improved method for casting letters. I find the elegance of this quite inspiring -- that Gutenberg did not invent 'the printing press' out of thin air but rather made this seemingly minor, but in fact absolutely crucial improvement that almost immediately propelled it from a niche technology into a cornerstone of intellectual life. There are many contemporary parallels...

(Incidentally, printing's rapid adoption was surely in part due to its usefulness not just for intellectuals, but also for the ever-present propaganda efforts of government officials.)

Printing supported not only governments, but revolutions. I have a hard time believing the American Revolution could remotely have happened without the printing press.

Consider the modern parallel of the Egyptian Revolution being enabled by Facebook.

Incidentally, printing's rapid adoption was surely in part due to its usefulness not just for intellectuals, but also for the ever-present propaganda efforts of government officials.

Not to mention the ability to print bibles, which was pretty important at the time.

In fact much revolutionary technologies come from small incremental improvements, and often were invented by several people at the same time : the telephone, the radio, the steam engine, television...
