A document processor is a document preparation system. Unlike a word processor, this type of application leads the author to concentrate on the structure of the document rather than its appearance. The author therefore focuses on what he/she wants to say, instead of fretting over page borders, font attributes, or formatting. Moreover, the author will be guided in the organisation, structure, and flow within the document.

LaTeX is a distinguished typesetting system which is designed for the production of scientific and technical documentation. It employs beautifully crafted typesetting algorithms. Academic journals will often accept submission in this format.
