//PrintContext
//! Allows setting options of a print job based on specific device
/*! \class PrintContext context.h "hpprintapi.h"
This object serves two purposes. First, it encapsulates knowledge about all
devices supported in available driver components. It can be queried at runtime
to determine capabilities of the attached device. Second, it allows for
setting optional parameters of a print job, such as media size and margins,
use of color and data-resolution, etc.

The PrintContext is the second item created in the driver calling sequence,
following SystemServices. It provides the interface for inquiring about
supported devices, and for setting all optional properties of the imaging
pipeline as determined by given devices.
