GoodDay!
i have a question, if it is possible?

i have a modem and 2 routers.one of my router1(4 port) connected to a modem(1port) to share INTERNET and router2(4port) is connected to router1.. in router1(there's a 3 computers and router2 connected) and router2(have a 4 computers)

my question is how to share PRINTER from pc1 on router1 to pc5 on router2? it is possible in file and printer sharing?Is Router 2 configured as an access point to Router 1? Does Router 2 assign IP addresses to its clients through its DHCP server or does it use Router 1's DHCP server?
Computers have to be in the same subnet on a LAN for them to communicate with each other.The important trick is to have only one DHCP in the system.
Example:
Let's say router #1 does DHCP and is the one right onto the modem. There router HAPPENS to be at
192.168.1.1 and the mask is
255.255.255.0 and the DHCP ranger is
192.168.1.2 up to
192.168.1.51
 and the PCs all shall get LAN IP automatically.

(Note: the DHCP range may vary. look in the DOCUMENTATION.)

In that case, I would set the other routers this way:
192.168.1.47     #2 router
192.168.1.48    #3 router
192.168.1.49    #4 router
Or just anywhere in the high end of the DHCP range.
For that matter, it works almost anywhere inn the range.
The PCs normally get the lower numbers.
Bear in mind, once you change the IP of any router you have to remember what is was if you ever want to log in again.
Does this help?
