i'm not going to find you a picture
but if your computers are all on the same router, you can set up a print server on any of the computers
for instance, on my desktop, i have a samsung laser printer, and any of my laptops can print off of it
all my computers share an internet connection through my wcg200, which is a cable modem, 4-port wired LAN and wireless LAN all in one box, about the size of a typical cable modem, and only cost me $69 at compusa.
