Why do you think that printing technology spread slowly from 1450-1470?

The slow spread of printing technology from 1450 to 1470 can be attributed to several factors. Firstly, the initial investment in printing presses was substantial, limiting access to wealthy patrons and institutions. Additionally, the demand for printed materials was initially low, as many regions relied on manual transcription and had established networks for book production. Finally, the lack of standardization in language and regional dialects may have hindered broader adoption across diverse areas.
