Fresh Install

This is my first time on the forums so sorry if I'm posting in the wrong place or if this has already been posted.
I just bought a refurbished MacBook off the Apple store and I was wondering if when I get it I should do a fresh install to delete languages, printer drivers, and other things I don't need. I heard other people do this but I was just wondering if it is necessary or if there is a way to manually delete these things without re-installing the software. Also, is it easy to do?

For the languages, install Monolingual and use that to delete extra languages. As for printer drivers, they are located at /Library/Printers. You might find this interesting to read.

I've removed both printer drivers and languages with Monolingual (read the instructions/README first) and everything went smoothly but it is always good to do a backup of your data first.
