Writing
Orthography or perhaps Literature...
The term "writing" describes any process of putting characters on paper to form words and linguistic constructs. In the western world, this means putting characters together to form words and sentences. In cultures using idiograms, each character used represents a word or concept.
The characters can be put on paper by hand using an instrument such as a pen or pencil; by typing characters onto paper using a typewriter, stored in an electronic medium such as word processing, etc.
"Writing" is also often used in a specialized sense, to describe the craft of creating a work of literature, whether fiction or non-fiction.
