Printing is the process of transferring text and images onto paper or other materials. It allows us to create books, newspapers, and posters, making information accessible to many people. The invention of the printing press by Johannes Gutenberg in the 15th century revolutionized the way knowledge was shared, leading to the spread of ideas and literacy. Today, printing technology has advanced significantly, with methods like digital printing and 3D printing. Digital printing uses computers to produce high-quality images quickly, while 3D printing creates three-dimensional objects from digital designs. Both techniques have opened new possibilities in art, manufacturing, and education.
