minimum drivers needed for lightscribe

Archived from groups: alt.video.dvdr,comp.sys.hp.hardware (More info?)

I recently purchased an HP DVDR640i drive (with "Lightscribe" ). I
already have Nero (version 6.6.0.15 - the latest version) installed on
my PC, which I know has some capability built-in for dealing with
Lightscribe drives. I have not installed the drive yet.

My question is, what is the minimum amount of drivers and/or software
that I need to install in order to be able to use Nero to access the
Lighscribe features on this drive? What I appear to have available are:

- The software CD that came with the drive
- LightScribe "host software" available for download from Nero's site
- A "Lightscribe Print Engine Update" available from HP's site
- A "Lightscribe System Software Update" available from Lightscribe's
site

Which of these (if any) are necessary to make Nero able to create
Lightscribe labels? I am reluctant to install the software from the CD
unless necessary, as I suspect it is going to install a lot of stuff I
don't really need.

Also, can anyone tell me what the difference is between the "host
software," "print engine" and "system software" downloadable from Nero,
HP and Lightscribe? Are these all different names for the same driver?
If not, can anyone tell me what these various pieces do?

Thanks,
Ethan
