He's at the age where he's discovered that he can jump up on things.
Please don't use a newspaper or spray bottle. It will either make him
scared of you, or just encourage him to do it when you're not
looking.

Try one of these non-direct methods, which will startle him but he
won't associate it with you. You can put sticky strips/tape on the
table or cookie sheets with some water in them (if he dislikes water)
to discourage him. You can also put a few pennies in empty soda cans
and line them up on the edge of the counter/table. When he jumps up,
they will fall and startle him.

Also, remove ALL tempting items, food, toys, etc, so it's not as
appealing to him. Make sure he has a tall cat tree that he can jump on
instead.
