Woodblock printing
Woodblock printing is a technique for printing text, images or patterns that was used widely throughout East Asia. It originated in China in antiquity as a method of printing on textiles and later on paper. As a method of printing on cloth, the earliest surviving examples from China date to before 220, and from Egypt to the 4th century.

By AD 593, the first printing press was invented in China, and the first printed newspaper, Kaiyuan Za Bao, was available in Beijing in AD 713. It was a woodblock printing. And the Tianemmen scrolls, the earliest known complete woodblock printed book with illustrations, was printed in China in AD 868; it did not supersede the use of block printing.

Dynastic histories were often written, beginning with Sima Qian's seminal Records of the Historian, which was written from 109 BC to 91 BC. The Tang Dynasty witnessed a poetic flowering, while the Four Great Classical Novels of Chinese literature were written during the Ming and Qing Dynasties.
Printmaking in the form of movable type was developed during the Song Dynasty. Academies of scholars sponsored by the empire were formed to comment on the classics in both printed and handwritten form. Royalty frequently participated in these discussions as well. The Song Dynasty was also a period of great scientific literature, and saw the creation of works such as Su Song's Xin Yixiang Fayao and Shen Kuo's Dream Pool Essays. There were also enormous works of historiography and large encyclopedias, such as Sima Guang's Zizhi Tongjian of 1084 AD or the Four Great Books of Song fully compiled and edited by the 11th century.

The Song Dynasty was a ruling dynasty in China between 960 and 1279;
Social life during the Song was vibrant; social elites gathered to view and trade precious artworks, the populace intermingled at public festivals and private clubs, and cities had lively entertainment quarters. The spread of literature and knowledge was enhanced by the earlier invention of woodblock printing and the 11th-century invention of movable type printing.

Writing is a precursor to printing and there wouldn't be printing if writing wasn't first.
Everything evolves and science has accepted that as fact.
I think that answers your question: Who'd seen or heard a printing press before Guttenberg started?
You have tossed in questions and then expect some other person to go do the research. I'm not going to research every question you have asked. I think this will do.
What you did was try to make a case by asking questions. That tactic is not going to work with me.
I'm new here and I'll be requiring links from you as a future reference.
