‘Level 1’ was added later to differentiate it from the more recent Level 2 upgrade. It was originally just called PostScript. It took Adobe 20 man-years to develop PostScript, a language that can be used to control output devices like laser printers. You sometimes see it mentioned in wine guides on maps of Napa Valley where some of the most famous Californian wines are made.Īt first, Warnock and Geschke thought of building a really powerful printer themselves but they soon realized that it would make more sense to develop tools for other manufacturers to control their printers. John Warnock and Chuck Geschke named their company Adobe, after a little creek that ran behind the house of Warnock in Los Altos, California. In the picture below Warnock is sitting to the left and Geschke to the right. When this failed, they decided to leave Xerox and try it on their own. ‘Chuck’ Geschke, tried for two years to convince Xerox to turn Interpress into a commercial product. He developed a language called ‘Interpress’ that could be used to control Xerox laser printers. One of the brilliant engineers working at Xerox was John Warnock. The laser printer, the graphical user interface, and ethernet are some prime examples. This is where many of the computer technologies we now take for granted were developed. The history of PostScript starts at Parc, the research institute of Xerox. Graphics could be done but the quality was only acceptable to the nerds that bought computers in those days.
If you owned a personal computer, you could hook it up to a dot-matrix printer that would output low-quality bitmap characters.
In most cases, it would even be difficult or impossible to exchange data with other systems. The Acme system would be incompatible with equipment from any other manufacturer.

Then you would follow at least two weeks of training to learn how to use the system. In the early ’80s, if you needed typesetting equipment, you went to Acme Typesetters, and they would sell you an Acme system with an Acme output device. To appreciate PostScript, you have to know how the market worked before it became available. Part of this overview is based on ‘Accidental empires’, the book written by Robert Cringely on the personal computer revolution. It has had a profound impact on the publishing industry and even today remains an important industry standard.įor more information on the history of prepress in general, please jump to this page. PostScript is now on the market for more than 25 years. These pages provide an overview of the evolution of the PostScript page description language.
