Improved printer support features

• Page device setup provides a device independent framework for specifying the requirements of a page description and for controlling both standard features, such as the number of copies, and optional features, such as duplex printing, paper trays, paper sizes, and other peripheral features.
• Applications developers will be able to write a single driver for a variety of different PostScript printers. The same code can be used to address printer specific features whether the features exist in the printer or not. If the feature is not in the printer, the application can decide how to best respond to the lack of the feature. Benefits: Enhanced functionality. ISVs benefit by having a more uniform method for accessing printer specific features. End users benefit by having software that will take advantage of their printer's features.
