In a short essay of at least 150 words, explain how the concept of books and printed materials is used as a theme in Don Quixote.

I would say:

Our knight lives optimistically in a fictitious, idealistic past. Sancho withal aspires to a better life that he hopes to gain through accommodating as a squire. Their adventures are ecumenically illusory. Numerous well-bred characters relish and even nurture these illusions. Don Quixote and Sancho Panza live out a fairy tale.Virtually all these characters are of noble birth and mystically enchanted with excellent appearance and manners, concretely the women. And everything turns out for the best, all of the time. And so, once again, they live out a fairly tale. Here we have a miniature fairy tale within a more immensely colossal fairy tale. Outside of the fairy tale, perhaps, we have the down-to-earth well-meaning villagers of La Mancha and a couple of distant scribes, one of whom we ourselves read, indirectly. I struggle to understand the standpoint of the narrator. Is the novel contrasting a day-to-day and mundane authenticity with the grandiose pursuits of the world's elites? This seems to be the knight's final clientele. As for reading the novel as an allegory of Spain, perhaps, albeit why constrain it to Spain?

the development of trade during the middle age increased to the change given in the agriculture, which gave money, industry and markets a bigger importance in economy. the agriculture production was more than the consumption, which meant the creation of wider markets out of the areas. besides, with the end of multiple wars, the population increased and new trade routes were created.
