   The thing to remember is to NOT look directly in the file named
'LaserWriter'. This may not be the users current printer driver. The
correct thing to do is look at STR resource -8192 in the system file.
This contains the current printer driver name. For a printer driver which
drivers a PostScript printer over AppleTalk, the driver's PAPA resource 
-8192 contains the printer name, type, and zone information necessary for 
obtaining a connection to the printer the user has chosen. 
   By not hardcoding the app to look only in LaserWriter but instead into
the current printer driver this allows the user to rename the LaserWriter
driver or to use a substitute driver, such as the one Adobe Systems is
developing as a LaserWriter driver substitute.

Hope this helps,
