Sharing a LAN printer over a subnet

Two scenarios for you:

1. 
   

   ROUTER1 / \ / \ PRINTER DESKTOP1 [96.96.96.10] [96.96.96.11]

   
   


2. 
   

   ROUTER1 / \ / \ PRINTER ROUTER2 [96.96.96.10] [96.96.96.11] [192.168.1.1] / \ / \ DESKTOP1 DESKTOP2 [192.168.1.11] [192.168.1.12]

   
   

My problem

• 
  

  In scenario 1, DESKTOP1 can completely connect to PRINTER.

  
  


• 
  

  In scenario 2, DESKTOP1 cannot connect to PRINTER. Why?

  
  

I'm assuming the problem has something to do with the configuration of ROUTER2. Seems like a simple problem, but am drawing a blank.

Appreciate any advice?
