Printing Crashes Rev in OSX

[Sivakatirswami]

Mac OSX printing greyscale to a Xerox Docucolor 3535.

The following seems to be a simple enough:

on printTranscript
   put the cHeader of me into tPrintTranscript
   put cr & cr after tPrintTranscript
   put fld "Transcript" after tPrintTranscript
   revShowPrintdialog, true,true
    revPrintText tPrintTranscript
end printTranscript

the "job" prints OK, but then, Rev crashes immediately after sending 
the data to the printer.

?? any clues?
