I suspect that the problem you are encountering is a ramification of
using StandardForm as your default output format type.  You can force
plain text to be used in Print and other kernel output cells by clicking
on the front end menu command sequence 

	Cell -> Default Output Format Type -> InputForm

or by evaluating an appropriate SetOptions[] command.

sets option on a global level

	SetOptions[$FrontEnd, 
          CommonDefaultFormatTypes -> {"Output" -> OutputForm}]

sets option on an individual notebook level

        SetOptions[EvaluationNotebook[],
          CommonDefaultFormatTypes -> {"Output" -> OutputForm}]          

If you wish to retain StandardForm for output, you could write an
override function for Print[] that does something similar to the
OutputForm.

Unprotect[Print]?

Remove[Print]

System`Print[expr___] := 
  CellPrint[
    Cell[TextData[StringJoin[Map[ToString[#, OutputForm] &, {expr}] ]], 
      "Print"]]

Protect[Print]
