How to use HoldForm within Module

Hello Mathematica gurus,

I am new to Mathematica. I need to use a function in its original form
within Module.

e.g.,doNOTCHANGE[f_]:=Module[{g},g=HoldForm[f];Print[g]]

may not give what I want as f is already rearranged according to
Mathematica's lexicographical order within Module,i.e.,HoldForm[f] in
Module may not be exactly of the same form as f as defined. One example
is f=-1(UnitStep[t-1]-UnitStep[t-2]).Can any of you out there show me
the way to get f in its original form inside Module?

Thanks
Chee
