Print not showing in ipython notebook

I had a similar printing problem when my first code cell was:

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

Then I’ve commented the second and third lines like this:

import sys
#reload(sys)
#sys.setdefaultencoding("utf-8")

Reset the kernel and re-ran the program and now my print statements are working properly.

Later on, I’ve found that when I was first having the printing problem, all print outputs were actually being sent to the ipython console terminal (on my Linux box), instead of being embed on the notebook.
