Printing is the task or activity of transferring a specific content or set of signs (letters, words, texts, figures) stored in a digital format onto any material support (paper, fabric, plastic, acetate, wood, etc.) for communication purposes. From printing, photographs, newspapers, magazines, books, letters, documents, brochures, and other graphic pieces can be made public. To perform printing, it is necessary to use some type of printer, an electronic device that transfers binary information to a physical surface through various means such as laser and ink. Virtual objects can also be printed in three dimensions, a process called rapid prototyping.
