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

Description:

GreEscape DEVESC_QUERYSIZE queries the size of memory (in bytes) required for the corresponding list of specified job property types.

Refer to Dynamic Job Properties for related information.
