Nivo Slider not printing - How do i get my nivo slider images printed out?

I can't print the nivo slider (default-theme): http://nivo.dev7studios.com/theme-demos/

I don't know why and I'm trying to get a solution for a few days now.

I tried stuff like

#slider {
  visibility: visible;
  width:      950px;
  height:     3开发者_运维技巧50px;
  overflow:   visible;
  display:    block;
  position:   relative; 
  z-index:    50;
}

in a print.css. Nothing works

I would be very happy if someone could have a look at it.

for printing images:
