An important goal when defining Level 2 was to “catch” existing language extensions and to fix a unified standard. This was necessary because Adobe had to extend the PostScript language several times in order to keep up with the printer hardware development:►The first color printers brought the PostScript color extension containing, among others, the CMYK color model (see Section 6.5) and new operators for colored raster images.►Connecting hard disks to printers for storage of fonts and system files demanded new operators for file input/output.►Composite fonts were introduced for the Asian market. They are intended mainly for Japanese with its large character set and complex glyphs.►Display PostScript extended PostScript to computer monitors. This way, PostScript is no longer restricted to static page descriptions but is also suited for dynamically driving window systems.
