For me it looks like a bug in gnome-control-center.
When clicking the button, it should be checked whether there is already
a system-config-printer process running. If so, the window of it should
be pulled to the front, if not, s-c-p should get started.
In addition, it must be made sure that the button action happens only
once when one clicks the button once, and not repeatedly as long as the
button is held down. The reports of some users that they get 7 instances
of s-c-p with a single click on the button looks like that in the few
milliseconds while they have the left mouse button down the action of
starting s-c-p is repeated in quick frequence.
So these issues need to get fixed in g-c-c.
