Pretending that Europe wasn't in a perpetual blood bath since the end of the Pax Romana until 1815 shows a gross ignorance of basic facts.
The printing press was a net positive in every time scale.

This shows that your understanding of history is rooted in pop-culture, not reality.
What "revolutions" were there in France between the ascension of Hugh Capet and the European Wars of Religion? Through that whole period the Capetian Dynasty stayed in power. Or in Scandinavia -- from Christianization on the three kingdoms were shockingly stable. Even in the Holy Roman Empire -- none of the petty revolts, rebellions, or succession disputes came close to the magnitude of carnage wrought by the 30 Year's War. This we know both from demographic studies and the reports of contemporaries.
In the long run the invention of the printing press was undoubtedly a good thing, but it is worth noting that in the century following the spread of the printing press basically every country in Europe had some sort of revolution. It seems likely that “Interesting Times” may lay ahead.
