Why? What are you trying to accomplish?
If I want to send a print out or PDF version of a Mathematica notebook to a colleague who doesn't have Mathematica and has no experience with Mathematica, then I would select all input cells and convert them to TraditionalForm (using cmdshiftT on a Mac) prior to printing or saving as PDF.
I have my notebook interface set so that input cells use StandardForm and output cells use TraditionForm. I prefer this since I don't need to remember special key combinations to enter stuff into input cells with StandardForm like I would with TraditionalForm. And I get output I find more readable without the problems a wrapper causes which occurs when you explicitly do
f[x_] := 4 x^2 + 2 x + 5 // TraditionalForm
That is
In[3]:= f[x_] := 4 x^2 + 2 x + 5 // TraditionalForm
In[4]:= Head[f[x]]
Out[4]= TraditionalForm
which is why the Plot command you use above doesn't display the expected plot.
Possibly what you want is something like
f[x_] := 4 x^2 + 2 x + 5 f[x]//TraditionalForm Plot[f[x], {x,\[Pi], \[Pi]}]
which would display the polynomial in traditional form and the plot as well. By setting my default preferences to have output cell display in TraditionalForm that is exactly what I get when I type f[x] without using the //TraditionalForm postfix notation explicitly.
