In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing. This method injects molten type metal into a mold that has the shape of one or more glyphs.

Computers and Typesetting is a 5-volume set of books by Donald Knuth published in 1986 describing the TeX and Metafont systems for digital typography. Knuth's computers and typesetting project was the result of his frustration with the lack of decent software for the typesetting of mathematical and technical documents.

In digital typography, the New Typesetting System (NTS) is a discontinued reimplementation of the typesetting system TeX in Java. The specific aims of the project were to continue the tradition of Donald Knuth's TeX by providing a first-class typesetting software which is both portable and available free of charge.

The Linograph typesetting machine was a "line casting" machine, modeled on the Linotype machine, that was used in letterpress printing. It was manufactured by the Linograph Corporation of Davenport, Iowa from July 1912 until sometime after 1938.

Hot Type was a Canadian television series, which aired weekly on CBC Newsworld."TV camera smiles on Evan Solomon".

<printer> A non-impact high-resolution printer which uses a rotating disk to reflect laser beams to form an electrostatic image on a selenium imaging drum. The developer drum transfers toner from the toner bin to the charged areas of the imaging drum, which then transfers it onto the paper into which it is fused by heat. Toner is dry ink powder, generally a plastic heat-sensitive polymer. Print resolution currently (2001) ranges between 300 and 2400 dots per inch (DPI). Laser printers using chemical photoreproduction techniques can produce resolutions of up to 2400 DPI. Print speed is limited by whichever is slower - the printer hardware (the "engine speed"), or the software rendering process that converts the data to be printed into a bit map. The print speed may exceed 21,000 lines per minute, though printing speed is more often given in pages per minute. If a laser printer is rated at 12 pages per minute (PPM), this figure would be true only if the printer is printing the same data on each of the twelve pages, so that the bit map is identical. This speed however, is rarely reached if each page contains different codes, text, and graphics. In 2001, Xerox's Phaser 1235 and 2135 (with Okidata engines) could print up to 21 colour ppm at 1200x1200 DPI using a single-pass process. Colour laser printers can reach 2400 DPI easily (e.g. an HP LaserJet 8550). Some printers with large amounts of RAM can print at engine speed with different text pages and some of the larger lasers intended for graphics design work can print graphics at full engine speed. Although there are dozens of retail brands of laser printers, only a few original equipment manufacturers make {print engines}, e.g. Canon, Ricoh, Toshiba, and Xerox. (2002-01-06)
