|You'll want to statically assign an IP to the printer. Don't use DHCP. |
Just check out the DHCP scope on the router and pick an IP outside of it. Typical router DHCP scope is as follows: 192.168.0.100 to 192.168.0.199
So, if your router's LAN IP is .1, I would use .10 for the printer. That's outside the scope of assignable DHCP IP's.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
