Simulation support:

This function is mandatory for hardcopy drivers and must be implemented in order to have a valid OS/2 hardcopy driver.

Refer to Dynamic Job Properties for related information.

Description:

GreEscape DEVESC_STARTDOC_WPROP will reset the device context information and presentation space information to be based on the new job properties that are passed in. This should be equivalent to the result of a new DevOpenDC with the new job properties.
