*       ^^^^^^^^^^^^^^^^^^^^^^    
*  
* YOu may have a problem here.  You never allocated prRecHdl.  So in short
*   you just passed a piece of garbage to a routine that NEEDS a valid handle.
*   What you need to do is this...
*
*      prRecHdl = (THPrint)NewHandle(sizeof(TPrint)) ;
*
*
*      Do this BEFORE calling PrintDefautl, which gives you the default fields
* for the printer selected with the Chooser.
