PrGeneral is a new feature of the ImageWriter (versions 2.5 and later) and the
LaserWriter (version 4.0) drivers which provides extensibility through a simple
procedure call. I need to determine inside my application whether the print
software the user has selected with the chooser has this feature implemented.
Is there a reliable way to get the version number of the driver in use? If not,
is the PrGeneral trap equal to the unimplemented trap in earlier software?
