Chapter 7 is about Typographic Technology. The invention of typography has been called the beginning of the Industrial Revolution, which is pretty monumental. The traditional method of setting type was hand composition, assembling individual pieces of type into lines. Linotype was one of the most profound developments in typesetting technology. The monotype machine cast one character at a time rather than an entire line. The ludlow, a semiautomatic linecaster, is another machine that found a place in the development of automated typesetting. In display phototypesetting machines light is projected through film negatives and a lens to expose letters, numbers, and other symbols onto a strip of photographic paper. See the image below for a reference. The two major types of keyboard phototypesetters were photo-optical and photo-scanning systems. They have the same basic components; the primary difference is how the photo paper or film is exposed. The two classes of digital typesetters are digital-scanning systems and digital-laser systems. Hardware is the physical components of the system. The electronic microprocessor chip does the work of the computer by receiving, processing, and storing information. Input devices generate information for processing by the cpu and display on a screen. A disk drive reads information from and writes information onto floppy disks. Output devices are used to convert to the screen. A laser printer creates images by drawing them on a metal drum with a laser. The instructions that tell the computer what to do are called software. The user interface has easy to use tools, permitting the user to focus on the task at hand.
