Advanced Printing Features
QuickDraw GX provides several features that allow your application to provide additional control for users and allows the application to take advantage of features in particular printers. These features allow you to

provide access to and perhaps modify the contents of a portable digital document or other print file
use different paper-type objects, including those created with the PaperType Editor
take advantage of a printer's built in features, such as fast text-streaming using built- in fonts by way of a direct job-formatting mode
directly specify methods of rendering data with alternative representations of QuickDraw GX graphics objects, such as with raw PostScript (These alternative representations are called synonyms, which are stored in tag objects. For a brief introduction of how you implement synonyms, see "Tag Objects" on page 1-24.)
set up halftones on a shape-by-shape basis by specifying halftones for the inks they use
provide users with feedback about vector device capabilities
examine the characteristics of a printer, such as its resolution and color-rendering capabilities
change the job properties if the user switched printers
change or prevent the display of the Status dialog box

The chapter "Advanced Printing Features" in this book describes each of these features.
