What large group of Europeans weren't able to the printing press?

A large group of Europeans who were largely unable to access the printing press were the rural peasantry and lower socio-economic classes, particularly in regions with limited literacy and education. The printing press primarily served the needs of the wealthy, educated elite and urban centers, where books and printed materials were more accessible. Additionally, language barriers and the high cost of printed materials further restricted access for these groups. Consequently, the spread of printed knowledge was uneven, favoring the upper classes.
