Answer by Josh Bode for How to make Ipython output a list without line breaks after elements?

An alternative to turning off pretty printing entirely is to increase the max_width trait for the PlainTextFormatter.

Add the following to ipython_config.py (find it by ipython locate profile):

c.PlainTextFormatter.max_width = 120

which will allow the pretty printer to use less vertical space by allowing lines to extend out to 120 characters rather than the default of 79.
