You need to use PBR to do this.
Deny the routes for the server/printer access from the PBR access-list and route all other traffic towards the axess-tel
access-list 100 deny ip 20.20.20.0 0.0.0.255 10.10.10.0 0.0.0.255
access-list 100 deny ip 20.20.20.0 0.0.0.255 30.30.30.0 0.0.0.255
access-list 100 permit ip any any
route-map axtess-tel permit 10
match ip address 100
set ip next-hop 20.20.20.150
interface vlan 20
IP address 20.20.20.1 255.255.255.0
ip policy route-map axtess-tel
You might need to edit the access-list if some access in future is required between some new vlans
HTH, rate if it does
