Simulation support:

This function is mandatory for hardcopy drivers, but may simply return a DEVESC_NOTIMPLEMENTED code. For other drivers, it is simulated by a handling routine in the graphics engine.

Description:

GreQueryHardcopyCaps stores information about the hardcopy capabilities of the device in the buffer addressed by pInfo. The information is stored as a sequence of one or more HCINFO structures defining the hardcopy capabilities for one or more form codes.

This function must be supported by hardcopy drivers. It is not required for display drivers. GreQueryHardcopyCaps is called by the function DevQueryHardcopyCaps.
