Typesetting ñ se usa mais. É coisa do passado. A 'mancha' da página era feita de letras de chumbo, em linhas inteiriças; a cada correção do A. ou do revisor de provas, toda a linha tinha de ser refeita e novamente 'chumbada' ou fundida. Hoje os livros são impressos em offset. O typesetting agora é 'imagesetter'.
imagesetter:
A machine that generates output for the printing process, which is either a film-based paper that is photographed or the actual film for making the printing plates. Input comes from the keyboard, or via disk, tape or modem. Earlier machines handled only text and were called "phototypesetters." Most imagesetters today support the PostScript language.
Modern imagesetters use lasers to generate the image directly onto the film. Older machines passed light through a spinning font photomask, then through lenses that created the point size and onto film. Others created images on CRTs and exposed the film.
The typesetter was originally the only machine that could handle multiple fonts and text composition such as kerning. Today, desktop laser printers are used for many typesetting jobs and are quickly advancing in resolution, although the 1,270 and 2,540 dpi resolutions of the imagesetter combined with the high-quality of film still provide the finest printing for photographs and halftones.

typesetting
Setting of type for use in any of various printing processes. Type for printing, using woodblocks, was invented in China in the 11th century, and movable type using metal molds had appeared in Korea by the 13th century. It was reinvented in Europe in the 1450s by Johannes Gutenberg. For much of its history, typesetting and printing were often performed by the same person, who arranged movable type, one character at a time, in rows corresponding to the individual lines in the publication and operated the hand press to imprint the image on paper. Typesetting was revolutionized in the 1880s with the invention of the "hot-metal" processes: Linotype (1884), in which the lines of type were assembled by use of a typewriter-like keyboard and each line was cast as a single slug of molten metal, and Monotype (1887), which also used a keyboard but cast each character separately. Photocomposition — the composition of text directly on film or photosensitive paper using a rotating drum or disk with cutout type characters through which light could be directed onto the receiving surface — appeared in the early 20th century. By the late 20th century, computers and publishing software generated characters and handled most hyphenation, layout, and other page-makeup decisions, with the resulting electronic file, including any graphics, passed to a laser printer for paper or film reproduction.
