Fullscreen button still visible on printing

[vincedchart]

Hi. This plugin is very cool but I can still see the special fullscreen plugin I use in printing, it's not hidden as it should. I give you all info about it

var map = L.map('map', {
center: [lat, lng],
maxZoom:maxZoom,
zoom: params.zoom || init.zoom,
layers: [mapbase],
zoomControl: true,
loadingControl: true,
fullscreenControl: true,
fullscreenControlOptions: {
position: 'topleft'
}
});

and the Javascript and css:

Thanks by advance
