In previous versions, you could highlight several different pages and then print "selection". This newer version does not seem to have this as an option when I go to my print screen. Is this something I can change in preferences?
You can still do this.
Just select all the pages on the thumbnail pane. Then right-click ([ctrl]-click on a Mac) on any of the selected pages, wait for the pop-up menu and select entry 'Print pages...' from the pop-up.
But you are right: nobody understands why Adobe changed the way of basically every single task you were used to get done from previous versions of Acrobat without any feelable improvement... ;-(
