“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.“The software featured in this article all produce high quality
professional documents. The majority of them rely on LaTeX as their
rendering engine. 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.“However, document processors are not only of practical use to
technical authors and scientists. This type of application will
help self-publishers to produce high grade documents, which survive
translation into multiple formats.”
