Dont generate emf-Files. Only a filed called "EmfVirtualPrinterPort".
Process bar in Word2007 exists only one time than Word must be restarted!
However emf-files are never generated!
It seems it cannot handle filenames with spaces, btw (even no processbar).
Changing the default nameing scheme under printer options is ignored also.
Tested on 2 Systems (both XP): in both cases the same troubles.
