The system had to produce images in full color for five projectors at 30 frames a second.Д®vans & Sutherland had never produced anything as complex. The trainees were to sit on the mockup of a shipвЂ™s bridge, surrounded by five 12-foot-high, 30-ft-long (3.6-by-9 meter) screens displaying a computer-generated representation of New York Harbor, complete with buildings, piers, movable buoys, changing weather conditions, and other ships to be avoided.

In 1971, Evans & Sutherland had undertaken to equip the New York Maritime Academy with a simulator for training harbor pilots. Six years of experience at Evans & Sutherland in Mountain View, Calif., had taught him where to start. from the University of Utah, joined the center in 1978, he immediately began work on a new printer protocol. It handled letters and simple images well, but for anything more detailed, got the printer to return the message: вЂњPage Too Complex.вЂќ Thereupon the typical PARC engineer would simplify the image.Д«ut when Warnock, a computer scientist with a Ph.D. They were controlled by a printing protocol called Press, which was not a programming language but a set of instructions that sent image data to a printer in a steady stream. Things were more elementary with the first laser printers, which were in regular use at the Xerox Palo Alto Research Center (PARC) in the mid-1970s.

On the same circuit board as up to 2 megabytes of ROM is a Motorola 68000 series processor, which executes the instructions and causes the pages to be printed.

There it is converted into instructions for the printer by the PostScript interpreter, software resident in ROM.

(Other page description languages are optimized for one of these purposes, not both.) That program is sent over a local-area network or through an RS-232 port to the laser printer. The PostScript program is created on the computer either by someone using the language or by desktop publishing software or other applications software that translates, say, the movements of a mouse into a PostScript program. It is as complete and flexible a programming language as Pascal or C or Forth, having variables, loops, conditionals, operators, and routines and offering any number of ways to get the same output. PostScript does all this implies-draws lines and curves, tilts text at arbitrary angles, or shades a photograph in various tones of gray. They can print many different type fonts and make the letters dance around the page hand in hand with drawings and photographs. But given more sophisticated software like PostScript, laser printers can do far more. Today laser printers are rapidly replacing the daisy-wheel printers in the office, pushing out letter-quality type as their laser obeys the commands of simple software.
