Rationale: + printing, when done wrong, can waste lots of time & paper => try to prevent printing without confirmation, as any number of this can go wrong + wrong printer + wrong range + wrong colour/bw setting (to only name the most common ones) + many other applications (e.g. GNOME applications, MS Office) also do not print without confirmation by default
