Is there a way to capture what is printed by public printer?
Sure. There are some mitigations for various threats (like TLS on the connection against MITM), but asked like that it can be clearly answered with "Yes".
is possible too, the same way.
shutting it off
Sure. If the printer can be shut off remotely at all, then an attacker can do it too.
