Add style to remove Drupal's admin toolbar when printing

The print style sheets should suppress the printing of Drupal’s admin toolbar. Edit your print.css and change this CSS rule:

/* Hide sidebars and nav elements */
#skip-to-nav,
#navigation,
.region-sidebar-first,
.region-sidebar-second,

by adding the #toolbar, to the beginning of that rule. Like this:

/* Hide sidebars and nav elements */
#toolbar,
#skip-to-nav,
#navigation,
.region-sidebar-first,
.region-sidebar-second,
