I have 2 subnet on the network, 192.168.10.x and 192.168.30.x.

192.168.30.x can ping .10.x and print from the printers on .10.x but 192.168.10.x can not ping or print from the other subnet (.30.x)

192.168.30.x --- GW - 192.168.30.4

192.168.10.x ----- GW - 192.168.10.5

The whole point of the Subnet Mask is to prevent the different Subnets from communicating.

If you have a main router using the 192.168.10.0 subnet and a second router as a "LAN client" of the main router and using the 192.168.30.0 subnet, this may let you access 192.168.10.x addresses from the main router, but it won't work the other way round.

You could try using the subnets 10.0.10.0 and 10.0.30.0 with the Subnet Mask 255.0.0.0 to see if that works the way you want. (Note the different Subnet Mask address used with 10.x.x.x addresses.)
