So, all your computers are behind the firewall and not connected
directly to the internet.  So all you have to do, is assign a permanent
IP address to the one with the printer.  You can either assign a static
address on the computer, or configure the router to always assign the
same IP address to that computer.  If you configure a static address on
that computer, make sure the address is outside the DHCP range, but
within the subnet range.
