Can u "delete" home networking?

Hey guys,

Here's the situation.

i have XP/32 and Vista/32 in my room. (both desktop)

First I set up my router Linksas WRT54G2 using Xp/32 machine and the set up went ok.

Second I brought Vista home and connected it to my XP machine and I was able to get on the internet from Vista (thank god)

But the problem is that I cant print from Vista machine even after installing my HP laserjet P1006 driver.

So my question is..... Is there a way to sort of "Undo or delete my networking cz i would like to start over again.

I also heard that if u set up home network again it will just OVERRIDE the original setup or setting.

If this is tru then obviously there would b no reason to "delete" the original setuo or setting.

So wat i'm saying is that i am very confused as to y i am not able to print from vista machine, i have no issue with xp.

and , i find out today that my Vista machine says that theres no driver installed for the printer.

I just wanna do some lil more homework on home networjing and start over again later time.

and lastly should i b worried bout anybody acceing my desktop through the network?

I dont no if i xplained that correctly since i am pretty new to the scene.

hey folks amy help would b appreciated.
