Error printing to Postscript Adobe Illustrator got an error: File/Fold

		end tell
	end tell
	
	-- set the text item delimiters back to what it was before we called the script
	set AppleScript's text item delimiters to TID
	
end printToPostscript

I get the error “Adobe Illustrator got an error: File/Folder expected”. If you watch the results it even writes the postscript file. It seems like it doesn’t know where to put it. I though that’s what the job options file path was for. A place to save the file with that path and name.

Any ideas would be appreciated.
Thanks
