get a full description of the page, only the text and fonts; users couldn’t

the layout of the text or adding graphic images was typically done by

a graphic artist who would physically cut and paste the document together

after it was printed, then send the pasted-up pages to a commercial printer.

The solution for Warnock and Geschke was to create PDL software that

would work for the PC and the printer; a common language that would not

only let the user manipulate the text, but enable any printer to print

what the user saw on the screen.

Creating a New Industry

the attention of Apple Computers, which was in the process of developing

a new laser printer for its Macintosh PC. By 1984, Adobe had revenues

of over $2 million, 68 percent of which came from Apple. Revenue for 1985

more than doubled when Apple Computers

introduced the Apple LaserWriter. This $7,000 laser printer came with

Adobe PostScript,

a PDL that gave the user more flexibility than ever before. Together,

Apple and Adobe had created desktop

publishing.

Adobe PostScript used a coded description of the page, including a mathematical

description of the text, to communicate directions to the printer controller

card, a Motorola 68000 microprocessor

with at least 1MB of memory. By storing fonts in an outline format description

rather than as a library of font sizes, text could be manipulated to appear

as white on black, shaded, a mirror image, or be stretched, compressed,

or manipulated to produce a variety of effects. PostScript language treated

the text and graphics identically. Because only one printer driver was
