2 wireless routers

I have two routers. One is a new linksys WRT160NL. The second is an
older asus with a wireless print server built in.

The Linksys is connected to my cable modem.

I want to connect an ethernet cable from LAN port to LAN port on the
two routers. Then, I'd like to wirelessly print using the internet
print server on the Asus, by sending prints to the IP address assigned
by the Linksys. I do _not_ want the Asus to be able to go out onto the
internet (no WAN), I just want it to be a LAN connection.

I know how to set things up on the Linksys side. I'm confused as to
what settings to use on the Asus. Below are my choices, and when I
used it as my primary router it was set as a Home Gateway.

Home Gateway: In this mode, we suppose you use WL500gP to connect to
Internet through ADSL or Cable Modem. And, there are many people in
your environment share the same IP to ISP.

Explaining with technical terms, gateway mode is , NAT is enabed, WAN
connection is allowed by using PPPoE, or DHCP client, or static IP. In
addition, some features which are useful for home user, such as UPnP
and DDNS, are supported.

Router: In Router mode, we suppose you use WL500gP to connect to LAN
in your company. So, you can set up routing protocol to meet your
requirement in office.

Explaining with technical terms, router mode is, NAT is disabled,
static routing protocol are allowed to set.
Access Point: In Access Point mode, 4 LAN ports and wireless devices
are set to locate in the same local area network. Those WAN related
functions are not supported here.

Explaining with technical terms, access point mode is, NAT is
disabled, wireless LAN and four LAN ports of WL500gP are bridged
together.
