Networking help?

Im trying to help my brother run a small office, and im not really getting paid for this just trying to help.
so anyways, he has a t1 line or t2 or whatever its called but all the computers connected via Ethernet cable, which is connected to a hub. so the website they used banned their IP (they only had one at first) and all the hits on the site banned the IP so he got multiple IPs with a range. Before the printer was connected with ethernet straight to the hub and all pcs had access but now since the IP is different on all computers the printer only hops on one IP and its only visible to that pc using the IP. the printer also has a setting where you can assign the IP your self but i tried some stuff i couldnt figure it out. help?
another option i used in the past was to connect the printer to one pc and share it with the rest but that way the scanning wont work as with the one IP config it works both printing and scanning. you can only share a printer not its scanning as i believe? anyways anything?
Answer #1
I think your confused with WAN IP’s and LAN IP’s.
All the computers on your local network should be on the same subnet and can directly communicate with each other, so they will all need a different IP.
The issue with your printer not talking to the local network is completely separate to websites banning your IP.
Answer #2
of course. ad the soltuion to the website banning the ip was to assign specific ips to each computer! not 192.68.1.1 ip.. like real ip’s for each pc
Answer #3
why waste paid IP’s use nat for outside and use what ever private ip u want inside.
