What term describes the learning of printing, writing, and spelling?

The term that describes the learning of printing, writing, and spelling is orthography. Orthography refers specifically to the conventional spelling system of a language, which includes the rules and patterns for writing words correctly. This encompasses not only spelling but also punctuation, capitalization, and the representation of sounds in written form.

Phonology involves the study of the sound systems of languages and how sounds function and pattern within such languages, making it unrelated to the actual written representation of those sounds. Semantics pertains to meaning in language—addressing how words and sentences convey meaning—rather than the mechanics of writing. Syntax is concerned with the structure and arrangement of words within sentences, which doesn't directly relate to the skills of printing or spelling. Hence, orthography is the correct term for the learning of printing, writing, and spelling.
