What download for minimum print drivers for HP CM1213NFI MFP printer?

I need to d/l the minimum software for the HP CM1312NFI MFP printer.

Here is HP's download page:

http://h20000.www2.hp.com/bizsupport...5&swEnvOID=228

Which do I choose?

All I want right now is the basic print capability, not the entire
kit.

I want to be able to print over ethernet and print over USB.

The terminology in the driver section is ambiguous. To me, "Network
Express Install" and "USB Express Install" sound like installation
media (or over the net) but maybe they mean what flavor of
printer-connectivity the software is specific to.


I've seen a Macintosh computer "find" an HP MFP printer on an Ethernet
and print to it without any added drivers. I assume it was LPR/LPRd
protocol which I use whenever I can. (This was for a HP model that is
now 3 years old.)

Is there any chance an XP or Vista WIndows machine can do that?
