window opens with os.system()

[jim-on-linux]

python help,

I'm testing on xpPro

I have a simple module that sends text files to a 
printer. Then, it moves the file to the 'Fprtd' 
directory. The module contains the following 
code;


#####

for n in PrtList:
  os.system('type '+n+ ' > prn'
  os.system('move '+n+ ' Fprtd')

##### 

os.system opens and closes a window for each file 
it sends to the printer and again for each time 
it moves a file to the Fprtd directory.  If there 
were only a few files, this wouldn't be so bad. 
But, when the files number 300 to 400 it becomes 
objectionable.

Is there any way to supress the flashing window.

xp no longer allows the 'ctty' command.
