[Discuss] CUPS Remote Printer

[Jeremy Kiffiak]

Murray,

Because you are not really needing the functionality of the router why  
not use the device as a switch instead?  Turn off DHCP serving on the  
2nd router and simply plug Router1 into one of the LAN ports on  
Router2.  Then plug Computer2 also into a LAN port on Router2.  Now  
both of your computer should be on the same LAN segment and be able to  
communicate with each other directly.  Enjoy.

Jeremy
