Stopping a fucntion from printing its output on screen

[sophie_newbie]

Hi, in my program i need to call a couple of functions that do some
stuff but they always print their output on screen. But I don't want
them to print anything on the screen. Is there any way I can disable
it from doing this, like redirect the output to somewhere else? But
later on in the program i then need to print other stuff so i'd need
to re-enable printing too. Any ideas?
